onesie

Snap-crotch baby garment

A onesie is a one-piece garment.

For infants, it's a bodysuit that snaps at the crotch for easy diaper changes.

For adults, it's a loose-fitting jumpsuit worn as loungewear or pajamas, often with a playful or cozy aesthetic: I spent Sunday in my onesie watching movies.

The plural is onesies.
