New Cycling Themed Clothing Brand - I need your help!

Ha! Did the survey and asked not to leave the girls out...personally I prefer to go for small men's size/more of a boyfriend cut as ladies sizes tend to be quite short in the body which isn't so great for drafts on your kidneys when on a bike!

That sort of confirms what I was thinking, out of interest what size would you go for if wearing men's tee's, if I went xs would they still be too small?
