When I worked for a personal styling company right after college (before I moved to New York), I learned all about the “third piece.” If you’re not familiar, it’s the finishing piece that completes your outfit. If your top and bottoms are your first and second pieces (the foundation of your outfit), your third piece is the cherry on top. This can be a blazer, vest, scarf, sweater, or even a cool accessory that pulls your outfit together (like a hat, piece of jewelry, etc.). Most often, though, at least in the midwest, it’s a jacket or a blazer.
