What real women actually like.
How a style site measures what real women actually like, one anonymous tap at a time.
How the site works
Two layers, one site
The content
Outfit ideas, haircuts and colour, style systems, personality-type style guides and the occasional trip back to the 1970s closet. The part you came for: ideas, confidence and a few laughs.
The reader signals
Layered on top of that content is something fashion rarely has: real preference data. One-tap tools under our photos let readers say what works for them, and across a large audience those taps show which silhouettes, lengths, colours and eras women genuinely prefer, as opposed to what a runway or an algorithm says they should.
What we measure
Small taps, big picture
Every signal below is optional. If you never tap anything, nothing is asked of you and the articles read exactly the same.
❤️ / 👎 on images
Love it or not for you? The quickest read on whether a cut, outfit or colour lands.
Save this
Saving a look to your own saves panel is a stronger signal than a like. Your saves stay in your own browser; we only count that a save happened.
Settle It polls
One-question polls: curtain bangs or none? Straight-leg or wide-leg? Grey blending or full colour? You see the reader split the moment you vote.
“Why?” follow-up
After a ❤️ or 👎 we sometimes ask one quick reason: the length, the colour, looks easy to maintain, wouldn’t suit me. That last one explains more than any photo can.
Hot or Not
Two looks side by side, pick one. Head-to-head picks rank styles far more precisely than single votes.
Reading behaviour
Which images were viewed, how far down a page readers scroll and how long they stay. Standard page analytics.
Privacy by design
What’s recorded, and what never is
Recorded with a tap
- A random session ID, created in your browser. It is not linked to your name, email or any account.
- Device type (mobile or desktop) and how you arrived (for example Pinterest, Facebook or a search engine).
- An approximate region (state or province), read from the network edge when the page loads. We do not store your IP address.
- If you arrived from one of our ads: the advertising platform’s own aggregate audience breakdown for that ad (the age-range and gender mix of everyone it reached). Never anything about you personally.
Never collected by these features
- Your name, email address or any account.
- Your IP address or precise location.
- Anything you type.
- Faces or identities. Images are described by their attributes (style, colour, era and so on), never by who is in them.
Newsletter sign-ups are separate and handled by our email provider. Advertising and analytics partners are covered in our Privacy Policy.
From taps to findings
How results are published
Added up, never singled out
We only ever look at totals and percentages across many readers.
You see the live split
Right after you vote, once enough readers have answered for the numbers to mean something.
Research needs hundreds of responses
Findings such as which haircut lengths women over 50 actually prefer, which jeans shapes are rising, and which “flattering” rules readers quietly reject are only published when the sample is large. Small groups are never reported.
The results come back to you
As better guides and research articles on women’s fashion, hair and personal style, grounded in what readers actually chose.

The findings on this site are the short version. The complete research reports, with every chart and the data behind them, live on our Substack.
Your choices
Taking part is entirely up to you
Simply don’t tap. Items you save live in your own browser, so clearing your browser storage removes them. For advertising choices and cookies, see the Privacy Policy.
