They do come in ladies sizes, but unfortunately they do not come in singlets. Here is a link for the shirt.|http://www.sierratradingpost.com/terramar-helix-t-shirt-upf-25-plus--short-sleeve-for-women~p~1505n/?filterString=search~terramar-helix-t-shirt-for-women%2F&colorFamily=27

I bought one in a ladies size for my wife (different catalog nunmber). It is very form-fitting, but she described it as true to size otherwise. The man's XL fit is snug on me, too, but that's the way many wicking shirts are designed. Hope that helps.
