The Trèsfit Girl Guide
How to measure, how each piece is designed to fit, and honest notes on stretch and coverage.
How to measure
Five measurements, two minutes.
Use a soft tape, stand relaxed, and measure over light clothing or underwear. Write the numbers down; you will need them per piece.
Demo photos. Final diagrams will show every measurement on varied body shapes.
Bust
Around the fullest part, tape level and relaxed, wearing a non-padded bra or none.
Underbust
Directly under the bust, snug but not tight.
Waist
At the narrowest point, usually just above the navel. Do not pull in.
Hips
Around the fullest part of hips and seat, feet together.
Inside leg
From the top of the inner thigh to the ankle bone, standing straight.

Our fit principles
Honest about how it fits.
Designed for a range of bodies
Fit is tested on different heights, bust sizes and proportions, not on one sample body.
Honest about stretch and coverage
Each product page will state how compressive a piece feels, whether it is squat-proof and where the waistband sits.
Between sizes?
Guidance will be given per piece once sample measurements are confirmed. In general: size up for comfort, size down for compression.
Tell us how it fit
Fit feedback from members, shared with permission, will appear on product pages to help the next woman choose.
No size chart values, model measurements or fabric claims are published until verified.
