I try not to leave negative reviews especially for clothes bought online as it's very "buyer beware" but this ad says "100%" in big letters above in the description cotton". That's why I bought it. It's not 100% and not 1% cotton, you can tell that immediately when you touch the fabric, and after wetting it there are no questions at all. It's 100% synthetic fibers, I'm thinking polyester or maybe a polyviscose blend but it's definitely not cotton, there's no label saying what it's MADE of, no list of materials, but anyone who owns an item made from natural or synthetic fibers can tell the difference Recognize immediately.Very disappointed, will not buy from this seller again.
