What do you call the things in the title?

I have no go to word for this!

Union suits?

Yep. Flap in the bottom and all.

Except not all of them have that flap. I wasn't sure if that was required for that name?

Do union suits require the flap on the bottom and/or otherwise a more specific form factor?

I believe that the "traditional" union suit had some crotch access (drop seat was just one style) , but that it is not required for the name. Although I suspect these days "pajamas" may be an equally acceptable term.

Pajamas is a huge category, though!

I begin to suspect I know why it's difficult to figure out a term for this. :)
