they're truly the perfect thing for when you want to feel like a vintage couch. (Honestly I'd prefer it if they were brighter. Kind of want to dye them green) The brand is Isabel Marant.
When I first modeled these for my roommates they just stared in horror and said "Oh god. Oh god." The waistline is weird; it's V-shaped, much like old-timey men's pants were. So I obviously need old-timey button suspenders to wear with them.
Of course I already happened to be wearing a floral shirt as well. Ideally though I'd wear my brown sweater vest and one of my flowy tunic type shirts with it.
