Unless you're going to the gym, leaving the house in a sweatsuit is never actually appropriate - even though that's what I wore to nearly all of my morning classes in college. And while I pretty much live in comfy separates at home (this sweet set, specifically), I often wish I could wear them out and about. My love of worn-in sweatshirts has been well documented, but when paired with a Hitchcock-inspired pencil skirt in the same material, I knew it would be a winning (if not supremely comfortable) combination.
