It took me way too long to parse this sentence.

“I’m sorry, I can’t hear you, son! I’m wearing a jacuzzi suit.”

I think Adam Savage has actually gone into this a bit on his YouTube channel, dude really likes space suits and have a lot of videos about them so I’m not even going to try to find which specific video it was

I would say, a space suit (Being a suit to protect a human agianst space), is clothing like, equipment, such the same as a suit of armour or CRBN suit. Where an EVA suit (Being a vehicle allowing mobilty in low/no gravity areas), is a vehicle like, mech suit, such the same as an exoskeleton.

Yes we generally only use EVA suits in space

Somewhere in the climax of Revelation Space (book by Alistair Reynolds), he describes the “suit” taking the character from the orbiting ship to the surface as “more of a spaceship with room for precisely one occupant”
