The fabric at the trim and shoulders is crepe, which isn't clear from the photo. much nicer in person than online. runs large. i wear a large in knit tops (36d and to hide a soft belly) but this large was too big. armholes showed my bra and it was rather wide and boxy. i'll exchange for a m because i think i'll get a lot of use out of it this summer. a casual tank with a little spunk. cute!
