“Soft, silky tank - runs small”

“I bought these tanks for the gym. The length is great - long enough to prevent unwanted skin showing when raising arms or bending over. The fabric has a nice "tonal" jacquard print to it - very pretty! They run small, however. I am 5'6" with broad shoulders and 36AA chest - it's a bit too snug around the torso for my taste; I am exchanging the Medium for Large. There is no internal shelf bra - which is fine w/ me, but when I ordered them over the phone the associate described them as having the shelf bra.”
