MyFit — Find the size that fits you

Standard size guides tell you "if your chest is 96 cm take an M". MyFit goes further: it considers the specific fit of the garment (regular, slim, oversize), your fit preference, age, and whether the fabric is pre-washed or not. The result is a personalised recommendation, not a generic range.

No, not automatically. The data you enter (height, weight, age, fit) stays in the browser during the session. If you have a Custoomy account, you can click "Save to profile" to store them: next time you use MyFit or FitList your data will already be pre-filled.

MyFit shows the main size and adjacent sizes on the visual scale. If you're exactly on the border between two sizes, the result includes a reliability score: a value below 85% suggests considering the larger size if you prefer a more comfortable fit. You can also change the preferred fit on the slider to see how the recommendation changes.

Yes. When you select "Woman" and the item is classified as unisex, MyFit applies a correction offset that accounts for the proportional difference between female and male body types on a straight cut. In general, for unisex items women tend to size down compared to what they would for a specifically female garment — MyFit already factors this into the calculation.

MyFit only works with products for which we have physically measured the sizes and entered the data into our catalogue. We currently cover over 150 blanks from the main brands (Stanley/Stella, Gildan, Sol's, B&C, Fruit of the Loom and others). If you can't find your product, you can use the manufacturer's size chart directly on the product page, or let us know — we add new products every month.
