I wore Small FOTL and the sleeves flared like crazy but the body was alright. (you can see in my photos). In AA tee's the body ,too, fit pretty well but the sleeves still had some flaring--but it was okay. I was wondering if I should order a guys XS or S threadless brand tee? Has the sleeve flaring issue been fixed? I'm 5ft 9in and skinny. Do you think the threadless brand tee will fit me well? If so would you advise XS or S? I like wearing my shirts fitted, not painfully tight or baggy.

Thank you so much for your help!!
