Fit guide

Sizes with measurements, not guesses. Every product page carries the garment measurements for that piece, laid flat, in centimetres and inches. This page shows you how we measure, so the numbers on the page mean the same thing as the numbers on your own tape.

Measure a garment you already like

The most reliable way to buy online is to measure something you own and wear often, lay it flat, and compare it with the table on the product page. Take every measurement on a flat surface, with the garment smoothed but not stretched.

1. Chest

Button the shirt, lay it flat, and measure straight across from armhole to armhole, one hand's width below the seam. Double that number for the full chest circumference.

2. Waist and inseam

Lay the trousers flat, front up. Measure the waistband from edge to edge and double it. For the inseam, measure from the crotch seam down the inside leg to the hem.

3. Sleeve

Measure along the top of the sleeve, from the shoulder seam to the end of the cuff.

How the same shirt reads in three cuts

Left to right: close to the body, regular, and relaxed. Same chest measurement can look like any of these three depending on the cut, which is why we print the garment measurement rather than a word like “slim”.

Between sizes

Take the larger one. Exchanges are free, and a piece that skims is easier to live with than a piece that pulls.

Where the numbers come from

We measure the sample ourselves and put the result on the product page. Until a piece has been measured, its page says so instead of showing a table. That is part of the KEPT standard.
