Something like the capes in Andor, I always liked the look. Any time I’ve looked up capes/cape jackets though, they’ve been too expensive or non vegan. Also boots, I’d wear those shin/knee high boots a lot too (idk what they’re called), but idk if I got the legs for those.
A cape or cloak can be fairly easy to make.
Thrift shops can have cheap sheets and blankets of sometimes suitable material, or on a lucky day, rolls or large remnants of good fabric even.
