I said this ran large because i bought a 16 and i normally need a size 18 (i'm busty) if the item doesn't stretch. but, a size 16 fit me. it's more straight and less blousy, but it does fit. so, if you like your tops a little less full of fabric and more tailored but loose, imho you can size down.

the fabric is rayon/polyester that's light and cool. it is semi-sheer but a white bra or nude bra would be fine. the top has a double layer in front. one solid and the over-lay of the embroidery. th
