Stretchy Zara crew neck tank in white (small/medium)

Really cute Zara crew neck tank in ribbed stretchy fabric! Condition is very good -- no pilling, as it's been worn just 2-3 times -- but there is a little rumpling around the neck and armholes. See pics. This is a small, but fits more like a medium, I think. Selling because, as a 34C, I find it slightly big through the bust (but I have a narrow back and shoulders). Length is roughly 20 inches when on my 32b mannequin.
