Lace, lace everywhere. It ruled the Fall 2008 runways, showing up at Roberto Cavalli, Derek Som, Dolce and Gabbana, Alexander McQueen--and especially Prada, who turned out full top and bottom ensembles with shades of orange, brown and nude. You can start lacing up now, as this is the one fall trend (unlike leather jackets or ankle boots) which make a nice summer-to-fall transition. A lace skirt is a good start--when the weather cools down, I like to throw some brightly colored tights under it.
