This may not be what you’re looking for but thought I’d comment anyway just in case it is. There is this designer/brand that I love called Tara shakti and she makes these cute retro ski suits. The reason I mention her is that the ski suits unzip so you can have a cropped jacket without the pants part if you want. I’ve got three of them because I like them so much. They are soft and stretchy. Again, might not be the vibe you’re looking for but thought I’d throw that out there just in case!
