FIRST: the fit
I usually order a small in Patty, despite most people saying it runs small. HOWEVER: I got a medium in this, and I am very glad I did! It fits perfectly - flattering and still snug fitting without being too tight.
For reference - I'm 5'6 and about 138 pounds.
It's so nice and bright in color, and is a nice thick material unlike most racerback tanks. The crochet back is great quality and real crochet, not lace.
