Slip dress, what used to be considered lingerie once, is now one of the most multi-purpose pieces of clothing you can possibly own. We've always known that it's great for warm weather but you can also now wear your slip dress in the winter.

The key to making your slip dress transition easily from season to season is — say it with me now — layering. Whether it's a t-shirt, a chunky knit or a jean jacket all you need to do to wear a slip dress during the colder months is pair it with another article of clothing. And the best part? You definitely already own one, if not all, of these basics.
