The lace on this looks like it would be stiff, but it isn't. it's soft and drapes nicely. i normally buy an xl (if it's not a knit) and so i did. the top will fit up to a size 18 in the xl because it is boxy and generous. it fit me perfectly and just tapered my body. it looks looser in the photo.

it's as see through as the photo. and, i wouldn't wear a cami under it. that defeats the purpose for hot weather imho. i think a nude bra works just fine. you can see the model is wearing a white bra
