It’s as easy as a dress and infinitely more stylish. So why save one-pieces for summer? Take a sleeveless jumpsuit into fall with light layers — a sleeveless jacket, a boyfriend blazer, a moto jacket, or no-baseball-y baseball jacket. Or opt for a more fall-appropriate onesie in an autumnal hue or print, or versatile neutral. Trust me, you’ll get just as much wear out of it as any fall dress.
