Weft

Shopping filters for "cotton" often include anything with a little cotton in it. Weft reads each product's actual fabric label and tags it right on the product photo, so you can see at a glance what's 100% cotton and what's mostly polyester. How it works Open a category or search page on a clothing store and click the Weft icon. Weft checks each product's fabric and adds a small tag such as "100% cotton", "60% cotton" or "Has polyester", with a color bar showing the blend. Anything that doesn't match what you're looking for fades out or hides. What you can do • Look for one material or several, or choose "All natural" for plant and animal fibers only • Set a minimum percentage, such as 100% or 95% • Avoid fibers you don't want, such as polyester or other synthetics • Allow a little stretch, so 2–5% spandex still counts as a match • See where an item is made, and show only items made in the USA • Open a product page to see its full fabric content and a short guide to each fiber • Have Weft open by itself on the stores you choose Works on most clothing stores, from large marketplaces to independent shops.
