I tried this on in the store on a whim. it is so flattering, soft, and pretty. i generally wear a size 12 and bought a l although the m might have fit, also: it's got plenty of room. the chiffon yoke is not particularly sheer and a nude bra strap is basically invisible, the jersey is adequately opaque so no camisole needed. my dimensions are about 40"  bust x 33" waist.
