Sequins decorate both the top and bottom of the corset along the edges, with little dripping stalactites (from the top) and stalagmites (from the bottom). Janet's corset has more sequins along the bottom than coming down from the top, at least in front. The sequins are sparse on the sides; on the front and back of the corset the sequins are more closely spaced (but still show plenty of black space), spangled in a rough "dripping" hourglass shape, with the most sequins at the top and bottom, with very few, very spread out in the middle. Don't overdo it; a solid spool-shaped pattern of sequins on the front of a black corset looks very silly.
