Women’s floor length black dress

Brand new (never worn) only tried on and wasn’t happy with the look. I am a street size 14/16, and I got this custom measured to myself, which is why I am unable to return this. It is closest to their size 20 on Missacc.com. Beading and sequins all over dress. Sleeves are more sheer than the rest of the dress. For reference, I am 5’7 and this could easily be worn with heels without a hem.
