Kenobi's outfit is a brown shirt under a white bathrobe with a leather belt, worn under a brown cloak or hooded dustcoat or something

Yoda's outfit is a grey towel.

I really don't think these two outfits resemble each other or were ever meant to. I think they just wanted yoda to look raggedy because we're supposed to think he's a homeless crazy person before the reveal.
