Other online shops like Zalando make it possible to filter for a material. For this reason I prefer buying at Zalando. I only like 100% cotton and most of the stuff at ASOS is cheap polyester. I’d like to be able to filter for 100% cotton! At Zalando they have “cotton” and “100% cotton” as filters. Else I have to look up the material separately for each item and then at some point I just end up getting frustrated and close the app.
