That for one. And Peter’s def a t-shirt and jeans type of guy (or whatever fabric they use in space). Something that’s comfortable, practical, quickly put on and not having worry about - it can tear, it can get bloodied or otherwise dirtied and he needs to be able to operate in it if necessary, since it could always emerge a combat or otherwise drastical situation at any given point. His clothes getting in the way or taking too long to put on are pretty much the last thing he can pay any attention to, but it also needs to allow some comfort.
TBH I’m surprised his uniforms are as complicated as they are. It doesn’t fit his usual dressing style and character.
(Then again, probably just bc the artists thought it looks cool, but tell ya, as simple as the v2 uniform looks, it takes forever to put on with the buttons on the jacket and all, so it’s ?? idek his uniform style should be far simpler to fit him tbh.)
bUT the point is he would never, ever put voluntarily anything like a suit on, he would feel super uncomfortable and ridiculous and basically it’d be so much fun for the other party.
