16 Summer Office Outfit Habits for Women That Bosses Deem Trashy and Unprofessional

Dressing for the office during summer can be tricky. You want to stay cool while still looking professional, especially when temperatures rise. Knowing which outfit choices to avoid can help you maintain your professional image while navigating the summer heat without compromising on style.

When the weather gets warmer, it’s tempting to relax your work wardrobe, but some summer style choices might send the wrong message in a professional environment. Finding the balance between comfort and office-appropriate attire helps you create a summer business casual wardrobe that works for any office setting.

FYI, thanks to AI imagery software, we’re able to create very specific fashion examples to illustrate the points being made. In some cases, imagery is exaggerated to hammer the point home.

1. Wearing see-through lace tops

While lace tops can be stylish, wearing completely see-through versions to the office crosses professional boundaries. Your colleagues shouldn’t be able to clearly see your bra or undergarments through your top.

For office environments, sheer tops need proper layering to avoid looking inappropriate. A simple camisole or tank top underneath creates a more polished appearance that works for professional settings.

If you love the look of lace, opt for pieces with solid lining or wear a neutral camisole underneath for coverage. This allows you to enjoy the texture and detail while maintaining workplace appropriateness.

The key to making sheer tops office-friendly is balance. For work environments, pair a semi-sheer blouse with a tailored skirt and minimal accessories to keep the look professional while still being fashion-forward.

Remember that office dress codes exist for a reason. Saving your most revealing lace pieces for evenings and weekends shows you understand the difference between party attire and professional wear.

2. Skipping bras altogether

While going braless might be comfortable for casual weekends, it’s generally not appropriate for most professional settings. You might want to embrace body positivity and freedom, but skipping a bra altogether can create an unprofessional appearance in office environments.

The issue isn’t about body-shaming but about maintaining professional boundaries. Visible nipples or excessive movement can be distracting and may undermine your credibility with colleagues and clients.

If traditional bras feel uncomfortable during hot summer months, consider alternatives. Lightweight bralettes, seamless t-shirt bras, or adhesive options can provide minimal support while maintaining a professional silhouette.

For certain outfits, you might get away with no bra if the fabric is thick enough or if you’re wearing structured clothing like blazers that provide coverage. However, this depends on your office culture and dress code.

Remember that professional attire isn’t about restricting your personal style but about creating appropriate boundaries between your work and personal life. You can still express yourself while respecting the professional atmosphere of your workplace.

3. Tiny ripped shorts as bottoms

Tiny ripped shorts might be perfect for a beach day or casual weekend outing, but they’re definitely not suitable for office environments. When you wear these to work, you’re sending the wrong message about your professionalism.

The excessive skin exposure from ripped shorts creates an unprofessional look that can distract colleagues and clients alike. Even in more casual office settings, there’s a line between relaxed and inappropriate.

Consider the practicality too. You’ll likely feel uncomfortable sitting in meetings or at your desk all day in tiny shorts that ride up or expose too much when you move around.

Instead, opt for knee-length shorts in solid colors or tailored capris if your workplace allows casual bottoms. These alternatives give you comfort in hot weather while maintaining a professional appearance.

Remember that your clothing choices at work reflect your attitude toward your job. Even during summer months, it’s important to dress in a way that shows you take your position seriously.

4. Flip-flops in the office

While flip-flops are becoming more accepted in some workplaces, they’re still considered unprofessional in most traditional office environments. Despite flip-flops trending for Summer 2025, they often create a too-casual impression that can undermine your professional image.

The casual beach vibe that flip-flops bring doesn’t align with most office dress codes. The sound they make when you walk – that distinctive flip-flop noise – can be distracting to coworkers in quiet office spaces.

Even as workplace dress codes have shifted following the pandemic, there’s a difference between comfortable and too casual. Opt for more polished summer footwear options instead.

You can still embrace summer footwear trends with leather flip-flops that look more elevated or stylish sandals that offer more support. These alternatives provide comfort while maintaining a professional appearance.

If you’re unsure about your office’s stance on flip-flops, observe what successful colleagues and managers wear. When in doubt, save your flip-flops for weekend outings rather than important workdays.

5. Wearing crop tops that show the belly button

Crop tops can be super cute for casual settings, but showing your belly button at work crosses into unprofessional territory. While fashion trends come and go, office dress codes typically maintain certain standards of modesty regardless of the season.

You can still rock crop tops for work by choosing longer styles that hit just below your belly button. This approach lets you stay on trend without exposing skin that might make colleagues uncomfortable.

Pairing crop tops with high-waisted bottoms is another smart strategy for the office. This combination ensures no midriff shows while still letting you embrace the crop top style you love.

Remember that in professional settings, showing your stomach is generally seen as unprofessional, regardless of how casual your workplace might be. Save the belly-baring looks for weekend brunches or happy hours.

If you’re concerned about comfort in summer heat, try flowy or slightly baggy crop tops paired with appropriate bottoms instead of tight, shorter versions.

6. Oversized graphic tank tops

Oversized graphic tank tops are trending for summer 2025, but they aren’t always office-appropriate. While casual oversized summer graphic tees might be perfect for weekends, they can come across as too relaxed for professional settings.

The loose fit and often bold graphics can make you appear underdressed compared to your colleagues. Even when temperatures rise, your workplace still expects a certain level of polish that oversized tanks typically don’t deliver.

If you love the comfort of oversized tank tops, save them for casual Fridays or pair them with more structured pieces. A flowy tank with an inappropriate graphic or slogan can send the wrong message about your professionalism.

Consider that many graphic tank tops feature phrases, logos, or images that might not align with your company’s culture. What seems fun or cute to you could appear juvenile or inappropriate to managers or clients.

You can still enjoy the tank top style at work by opting for plain, more fitted versions or layering a cardigan or blazer over top for a more put-together look.

7. Neon-colored leggings instead of pants

Leggings have their place in casual settings, but neon-colored ones can be a major office fashion faux pas. The bright, attention-grabbing colors are simply too distracting for professional environments.

Remember that leggings, regardless of color, are technically not pants. They’re often too revealing and form-fitting for office dress codes, even in more relaxed workplaces.

The neon factor takes this issue to another level. Lime green, electric pink, or highlighter yellow leggings draw eyes for all the wrong reasons. They can make you appear as if you’re heading to a workout class rather than a business meeting.

If you’re drawn to color, try incorporating it through more appropriate pieces like a structured blouse or tasteful accessories. These allow you to express your style without crossing professional boundaries.

For bottoms, stick to proper trousers, knee-length skirts, or dark-colored, thicker leggings paired with longer tops that cover appropriately. This approach lets you stay comfortable while maintaining a workplace-appropriate appearance.

8. Visible thong straps showing

The exposed thong trend might be making waves in celebrity fashion circles, but it has no place in a professional office environment. Visible thong straps create an unprofessional appearance that can seriously undermine your workplace credibility.

While stars like Charli XCX and Billie Eilish might be bringing back this 2000s trend for red carpets and music videos, your office isn’t the place to experiment with this look. The infamous “whale tail” might be trendy in some circles, but it’s inappropriate for business settings.

Even if the peek is accidental, it creates an uncomfortable situation for colleagues. Low-rise pants or skirts that reveal underwear when you bend or sit down should be avoided entirely for work.

Always check your outfit from all angles before heading to the office. Do a quick sit-down test in front of a mirror to ensure nothing shows when you’re seated at your desk or in meetings.

If you love lower-rise bottoms, pair them with longer tops that won’t ride up, or consider seamless underwear options that won’t create visible lines or unexpected peeks.

9. Bed hair left completely messy

While the tousled look can be trendy for casual settings, untamed bed hair has no place in a professional environment. You should always ensure your hair appears intentionally styled rather than like you just rolled out of bed and rushed to work.

Messy bed hair can make you appear unprepared and unprofessional to colleagues and clients. It suggests you didn’t take the time to prepare properly for your workday, potentially reflecting poorly on your work ethic.

Simple solutions exist for those busy mornings. Keep a small hairbrush in your desk drawer for quick touch-ups, or opt for elegant summer hairstyles that stay neat throughout the day.

Even on the hottest summer days, a sleek ponytail, neat bun, or well-brushed waves can elevate your office style significantly. These styles keep you cool while maintaining a polished appearance.

Remember that your hairstyle is part of your overall professional image. Taking just five extra minutes in the morning to tame those locks can make a world of difference in how others perceive you in the workplace.

10. Too much glitter makeup

While a touch of shimmer can brighten your look, going overboard with glitter makeup at the office can be distracting and unprofessional. You want your work to shine, not your face.

Summer often inspires more playful makeup choices, but save those galactic glitter makeup ideas for weekend festivals or evening events. In professional settings, subtlety is key.

Heavy glitter on your eyelids, cheeks, or lips can give the impression that you’re headed to a club rather than a meeting. It can also be messy, with sparkles falling onto your face and clothes throughout the day.

If you love a bit of shimmer, opt for products with fine, subtle shimmer rather than chunky glitter. A light dusting of illuminating powder or a hint of pearl eyeshadow can give you that summer glow without looking excessive.

Remember that your office makeup should enhance your professional appearance, not detract from it. You want colleagues focusing on your ideas and contributions, not wondering if you forgot to wash off last night’s party makeup.

11. Excessively large hoop earrings

While hoop earrings are classic accessories that have never actually gone out of style, the oversized versions can be problematic in professional settings. When they’re the size of bangle bracelets, they can give off an unprofessional vibe in more conservative office environments.

The issue isn’t just about appearance. Large hoops are notorious for getting caught on clothing, especially during workplace interactions like handshakes or hugs with colleagues, creating awkward and sometimes painful situations.

Consider your specific workplace dress code before wearing statement hoops. If you work in a relaxed environment where coworkers wear jeans and casual attire, larger hoops might be acceptable.

For professional settings, opt for smaller or medium-sized hoops that complement your outfit without overwhelming it. You can still express your style with structured bags and professional footwear paired with more modest earrings.

Remember that the overall outfit matters too – the same earrings that look polished with business attire might appear inappropriate with very casual clothes.

12. Military boots with office skirts

While combat boots can look effortlessly chic with many outfits, pairing them with office skirts often creates a jarring style disconnect that reads unprofessional. The chunky, utilitarian nature of military boots clashes with the polished aesthetic expected in most workplace environments.

You might think you’re making a fashion-forward statement, but your boss and clients may view this combination as inappropriately casual. Even when styled with longer skirts, combat boots can give off a rebellious vibe that undermines your professional image.

For office settings, opt for more refined footwear like pumps, loafers, or sleek ankle boots that complement rather than contradict your skirt. Save your combat boots for weekend outfits or casual Friday when paired with appropriate pants.

If you’re determined to incorporate combat boots into your work wardrobe, consider wearing them with tailored pants instead of skirts. This creates a more cohesive look while still allowing you to express your personal style without crossing into unprofessional territory.

13. Wearing miniskirts that barely cover the butt

While miniskirts can be stylish, there’s a fine line between fashion-forward and workplace inappropriate. When your skirt is so short that it barely covers your bottom, you’re crossing into unprofessional territory.

Remember that sitting down makes any skirt ride up even higher. What seems manageable while standing might become a real problem once you take a seat at your desk or in a meeting.

Micro miniskirts might be trending in the fashion world, but they’re generally not suitable for office settings. You don’t want to be constantly tugging at your hemline throughout the workday.

If you love the miniskirt look, try opting for pleated styles which tend to have more movement and coverage. These can be paired with blazers or blouses for a more office-appropriate outfit.

A good rule of thumb: if you’re wondering whether your skirt is too short for work, it probably is. You want colleagues to focus on your professional contributions, not be distracted by your outfit choices.

When in doubt, try the fingertip test – if your skirt is shorter than where your fingertips reach when standing with arms at your sides, it’s likely too short for the workplace.

14. Sheer dresses with no slip underneath

Wearing sheer dresses to the office without a proper slip underneath is definitely a workplace fashion faux pas. When light hits these transparent fabrics, they can reveal far more than you intended to your colleagues and clients.

A slip creates a more flattering silhouette and prevents your undergarments from being visible. Slips enable your garment to move better over your curves, creating a more professional appearance overall.

There’s nothing unprofessional about wearing shorts under skirts or dresses for comfort and modesty. Products like slip shorts can be perfect for warmer weather while maintaining your professional image.

While sheer dress outfits might work for casual summer settings, they require proper layering for the office environment. Many retailers offer professional work dresses that balance style with appropriate coverage.

Remember that maintaining professionalism means being mindful of transparency in your clothing choices. When in doubt, do the light test at home before heading to work.

15. Overexposed cleavage with low-cut tops

While you want to stay cool during hot summer days, revealing too much cleavage at work is generally considered unprofessional. Bosses have named low-cut tops as one of the biggest mistakes a female worker can make.

You don’t need to wear a turtleneck to look professional, but a deep v-cut down to the belly button is better for non-work wear. The office environment typically calls for more modest attire.

A good rule of thumb is that if you’re constantly adjusting your top or worrying about leaning forward, it’s probably too revealing for work. Even in casual workplaces, maintaining a certain level of modesty helps preserve your professional image.

There are clever solutions if you love low-cut tops. Consider using accessories like scarves or layering with camisoles to make revealing tops more office-appropriate.

Remember, you can still look stylish and show your personality without crossing into inappropriate territory. Save the plunging necklines for after-hours events and weekend activities.

16. Brightly colored chunky sneakers

While colorful sneakers have become a streetwear staple, they can come across as unprofessional in office settings. Your neon green or hot pink chunky sneakers might be perfect for weekend brunches, but they often clash with the business atmosphere.

For work environments, it’s better to opt for low-profile sneakers with clean, simple designs. Chunky or overly sporty styles can appear too casual and distract from an otherwise polished outfit.

When choosing sneakers for work, neutral colors like black, white, grey, or beige are more versatile and professional-looking. These colors blend seamlessly with your work attire without calling unnecessary attention to your footwear.

If you love the comfort of chunky sneakers, save them for casual Fridays or swap them for sleek loafers or kitten heels to make your outfit more professional. Remember that maintaining a polished appearance includes your choice of footwear.

Always ensure your sneakers are clean and well-maintained. Scuffed or dirty sneakers can make even the most appropriate style look unprofessional.
