White ASOD bodycon dress with open back

ASOS white bodycon dress with open back. Size medium. I wear a 6 and it fits me perfectly. The pattern looks a little like lace/crochet but with polka dots. It's a really subtle pattern. The dress has two layers so it feels thick and is really high quality. The right armpit has slightly off yellowy coloring but isn't noticeable at all. I wore it to a formal once and have never worn it again! Open back with a tie. Super cute and flattering
