The idea of sheer fabrics and loose fabrics have always appealed to me. Obviously I'm not talking about a completely sheer cling film maxi-dress, I mean the beautiful lace trims on a pencil skirt, or the semi-sheer chiffon shirt...
Peekaboo accents on tops are just beautiful. Whether it be lace with a crop top underneath, or chiffon with a lace triangle bra. Always super feminine when toned down on the bottom half. (Or basically, the boobs or legs rule.)
