Madewell Lightspun Button-Front Mini Dress size small So easy to wear everywhere and anywhere (really, it's made of our best-selling supersoft Lightspun double-layered cotton gauze that resists wrinkling), this button-front mini dress has a flattering V-neck and extra-convenient pockets. Small black dot on dress because of how it lays its not noticeable. I’m sure can come off with stain remover (see last photo)
