SHEIN polyester dress multicolored with long sleeves- size 12 fits like 6 or 8

Beautiful unlined collared wrap dress by SHEIN in multipattern and multicolored. Long sleeves with button cuffs. New without tags or original packaging. I purchased new from SHEIN expecting a 12 as marked but this dress is sized closer to 6 or 8 so please note measurements. Approximate measurements: Pit to pit 19” Skirt length below waist to hem. 22” Adjustable waist and chest because of wrap belt! Great for office, wedding or night out!
