I'm average size, in between M & L, bought large & it was super tight but the armholes were ridiculous. They like bulged out about halfway down in the front. Thought maybe it was mis-sewn but I bought other colors & they all did the same thing.

Pretty color, I got the serene blue. Glad I sized up to a medium! I almost got a small. Still a little snug, but looks fine. I am a 4, (34C). 5'4" 124 lbs.

Love it! Comfy and form fitting! It was exactly what I wanted for the summer. I need 5 more! True to size

I love these tank tops, I bought 2 size small and wear them with a sports bra for when I go to the gym. I bought medium in 4 other colors and my bra shows on either side of the arm hole of the top. I'm 34B and have no idea why this happens with all Gap sleeveless tops. I bought two boat neck tops, size medium and gave them to a friend because my bra shows. My bad for not trying them on in the store. Glad I got a great discount on them because I doubt I'll be able to return them.

Fabric and style are OK, but the fit is very tight, almost compression like. I usually wear a S. I ordered a Med and it was still too tight. If I were to exchange them, which I won't, I think I would try an XL to get a comfortable fit. I'm tall and don't like tight clothes so a L might fit but would still be uncomfortable and short for me.

Perfect for spring and summer! It compliments my body so well. The material is soft too!
