Slip dress is a perfect foundation for layering. You can easily wear a pair of jeans underneath your dress or a chunkier sweater above it. For me, one of the best ways to wear the slip dress in autumn season is by pairing it up with a turtleneck. Also it is such a great way to extend your summer closet. It is one of those pieces for just about any occasion really.
