Brand new never worn! Carolyn mule flats in canvas with ruffle A backless version of our Carolyn flats—these mules give us minimalist '90s vibes in all the right ways. New this season in canvas with a fun ruffle detail. With an almond-shaped toe (aka not quite a ballet, not quite pointy), these will be your go-to shoes that are basically like slippers you can wear out of the house.
