FAQ:

Q: Are union suits still a thing?

A: Union suits are still commercially available, but because of their long association with “old fashioned” usage, and presumed “unsophisticated” rural wearers, they are considered comical. The rear flap is also associated with humor, and in film and television the appearance of a union suit, viewed from behind, is a form of mild toilet humor.

Q: What does union suit Mean?

A: What does union-suit mean? A one-piece undergarment combining shirt and long pants. (noun)

Q: What is about the union suit?

A: The union suit, also known as the onesie with the flap in the back (or waffle knit thermal), is perfect for winter wear. Designed to keep you cozy, it provides a base layer for your outer clothes so you can stay nice and toasty. However, finding a union suit that fits your body to the tee isn’t always easy.
