Vintage chocolate brown Sonja Blake wool skirt

Bought from my local vintage clothing store! Chocolate brown and fits like an XS. Cute button detail on back. Guessing 1970s strictly from the color scheme, but also looks similar to 1940s style skirts. Could not find info on designer. Skirt has no details on care instructions or fabric make-up, but I would guess it is wool or wool blend. Inside lining was torn when I bought it, but doesn't bunch or feel uncomfortable. I would guess a seamstress could easily fix it for you!
