Everyone has that one item in their closet that they wish they could wear every day. For some, that item is a perfectly lived-in pair of jeans. For others, it's a simple white T-shirt. For me, it's a silk slip skirt. The first slip skirt I owned was a black version from Vince. I remember contemplating splurging on the skirt for quite some time, but once I did, there was no turning back.
