Union Suit in Black/Red/Heather Grey from Nasty Pig. Introducing the most versatile Nasty Pig underwear ever. Wear 'em everywhere you want to be: under your jeans when you hit the streets, paired with a sick set of high tops and not much else when you're on the town, or with nothing at all, next to a roaring fire on Christmas morning. The snap closure that runs down the chest and then all the way around the back - to just above the butt - is an innovative back closure solution. It looks much sexier and more sophisticated than any flap ever could. Finished with a tone-on-tone NP logo on the left chest, and made of our super-soft, top quality spandex/cotton underwear fabric. You won't want to take it off.
