Finding clothing by composition online is harder than it should be.

Every product page shows a label somewhere, but actually finding garments based on the materials you want — and filtering out the ones you don’t — often requires opening dozens of tabs, scrolling through product descriptions, and manually checking fabric lists. If you care about what your clothes are made of, the process quickly becomes frustrating.

We believe it shouldn’t be this way.

By Composition was created to make fabric-first clothing search simple. Instead of browsing endless pages and discovering too late that a “wool sweater” is actually blended with synthetic fibres, our platform lets you search directly by the materials that matter to you.

Looking for 100% wool, pure cotton, or cashmere without synthetic blends?
You should be able to find it immediately.

Our goal is simple: remove the noise.

We curate garments from across the web and structure the information in a way that lets you filter by composition clearly and quickly. No guessing, no digging through hidden labels, no marketing tricks around materials.

Just real fabrics, honest garments, and clear choices.

This is only the beginning. By Composition will continue to improve how clothing can be discovered — putting transparency and material quality back at the center of fashion search.

If you care about what your clothes are made of, you’re in the right place.

Welcome.
