Marine Layer Lexi Rib Daytime Midi Dress in Black - S NWT, no flaws. We took our classic Lexi midi dress (you know, the tight one), and updated it in a thicker fabric (read: more slimming powers.) This daytime gem is slightly casual, slightly dressy, and insanely comfortable. Our bestselling Lexi Rib fabric (you know, the stretchy ribbed one with the magical slimming powers) is something to write home about. It has the thicker, more substantial 2x2 rib structure you've come to love and is made with sustainable TENCEL™ Lyocell fabric, plus a bit of Spandex — so it's comfortably fitted, flattering and insanely easy. 95% TENCEL™ Lyocell, 5% Spandex Machine wash cold, tumble dry low Approximate Flat Lay Measurements: Bust: 15.5" Waist: 14" Length (Shoulder to Hem): 44.5"
