3.1 Phillip Lim Blue Belted Poplin Dress

Short puff sleeve structured midi dress in cotton poplin, with a v-neck and elasticated cuffs. Features contrast stitching, a belted waist with eyelet details, and a flared full skirt. Asymmetrical hemline.

As worn by Jodie Comer on Killing Eve. It's a US 4 or UK 8. It also fits me and I'm a 10, as it's roomy!
