Hello ladies! I need help. I am very skinny on top (I've actually lost a lot of weight this summer that I see my six pack - even though i haven't hit the gym since May lol). I'm wondering if anyone knew if there are certain brands that might carry a few great-fitting xs sizes or companies whose shirt sizes run small. The only one that ever ran small for me was Abercrombie XS - except I am way too old to be wearing Abercrombie dress shirts - when you wash them the material becomes.... just not professional. Anyway, the problem with AF fittings were that their arms were way too tight for their own good. I am mostly concerned with ones that fit my practically non-existent chest, but overall, I pretty much have a very flat stomach and tiny arms. Also, I can't wear petite sizes because i'm 5'6 and the sleeves will seem too short, I also like shirts not too short because I don't like them coming out of my pants after I tuck them in. Anyhooooo. Thanks in advance!!!
