Review on Stylish NFASHIONSO Womens Cotton Cardigan: Perfect Women's Clothing for Swimsuit Cover-Ups by Prathima Rrain

I received black and white. I was skeptical because of the bad reviews but it is like the picture. Some people say it's polyester, not cotton. I saw a photo of the label in the review that said polyester, but mine says cotton. May be from different factories, maybe a mistake, but I don't know how to tell the difference other than drying it out and risking shrinking it. It's "one size" but for a flowy look this would be best for L/XL (maybe M but would be a bit large). I only gave 4 stars because - who knows what it's made of - any normal piece of clothing should be machine washable.
