It took me a while to make the connection, but any skin this touches I get an awful, swollen, long lasting rash. The tag says 100% polyester, so I'm not sure what is irritating me. I'm afraid to wash it because of the delicate weave, but maybe it's covered in itching powder? Who knows. Its pretty and I love to wear it until the swelling and redness starts. I don't have this problem with clothing ever, but I'm afraid I may not be able to keep using this.See full review
