Sparkly, backless body con mini skirt

Perfect for holiday parties. Sparkly, sequin-y body con dress with a boat neck and a plunging back. Three-quarter sleeves. Hem hits above knees. Smooth liner inside. Bought from ASOS, brand is TFNC London. Size tag is nowhere to be found but the dress was a bit too tight for me, and I wear either 6 or 8 in dresses. Never worn.
