The runways, much like the stage, are often used for showing a big idea, sometimes in an outlandish way. Like any form of art we are supposed to interpret it in our own way. So, when Madonna wore a black sheer lace dress with nothing underneath it but a bustier to this year's Vanity Fair Oscars Party, well, it was just too much. Lace has been a strong trend over the past few years and the beauty of this trend is that it can be demure--a lace blouse with a pencil skirt is suitably pretty for the office--or it can be sexy when it's sheer in just the right places. Madge's look--sheer all over with a slit all the way up the thigh--is too provocative, even for the original provacateur herself. Opaque black tights under this ensemble would have made a world of difference. Check out our dos and don'ts for wearing lace below.
