What better way to give the impression that you put effort into your outfit but in reality laid around in a towel until you were 5 minutes late and threw clothes on than with a jumpsuit? (Not speaking from experience at all.)
It’s true that jumpsuits and onesies are a staple in infantile clothing, and they do pose a bit of an issue when your bladder feels like a watermelon that someone’s slowly adding rubber bands to, but they look really good on most people. And, they’re really easy to take off at the end of the day when you’re over looking like a fancy baby with a job. Yeah, you don’t get to have all the fun of being half-naked with one fell swoop, babies.
