Choies black and white strip dress

Choies black and white asymmetrical strip dress. Stretchy material with zip back with back slit. Size listed as a XXXL but this dress runs small see measurements. Measurements were Taken flat and are approximate. 20 armpit to armpit, 18 bust, 35 3/8 front length and 36.5 back length and 20in hip. No care instructions, I would wash in cold water and hang it to dry.
