Aidan Mattox beautiful blue cocktail dress with sequins NWOT

Aidan Mattox NWOT beautiful blue cocktail dress with sequins. Tag says Sz 8 but mannequin is a Sz 6 and won’t zip all the way up. Mannequin is a 34C so this would be best for a size 4 or 32 bust. Beautiful dress so sad it didn’t work for New Years party. Built in bra. Never worn.
