Pet peeve: Those are called “sleepers”, not “onesies”. Onesies are t-shirts with snaps in the crotch. (Actually, I should say Onesies™, because it’s a registered trademark belonging to Gerber Products.)
I have no idea why so many people seem to have suddenly forgotten the perfectly good word “sleeper” and substituted a brand name for a completely different garment. It’s like if everybody decided one day that overcoats were called “fruit-of-the-looms”. Please could we just call it what it’s called?
