Despite our obsession with silver this week we still have a place in our heart (and our closet) for gold, like this gilded gold strapless dress.     Christian Lacroix showed gilded gold pieces on his Fall 2009 runway and while we love his runway styling of a black lace underpinning and black lace nylons, we'll keep it simple with a pair of opaque tights.     H&M does a brocade version of Christian Lacroix's strapless number for only $49.95.
