GU Sports Crew Neck Size: S I was wearing men's sizes instead of women's. I think it's okay for both men and women. I bought it for the gym, but my lifestyle changed and I haven't had a chance to wear it, so I've been storing it. I've worn it a few times. I think it's in good condition, but this is my personal opinion, so please check the photos carefully and purchase it if you are satisfied. Please understand that there may be some oversights as it is not new. It will be shipped in simple packaging. I also have shorts and other items for sale. How about it for exercise from now on?
