New Hello Molly Laces Black Dining Dress, Tag on

Bought this from Hello Molly and wasn’t able to fit in, they only approved returns with store credit which I disagreed, decided to just sell it back for anyone in need. Very cute and elegant dress with nice lace patterns. The tag said size 6 and was listed as size XS but I think it was size XXS. My body has been stable and only fits XS so I think their estimate XS is totally off. The dress is a just bit above my knee (I am 4’8”) Casual, formal, dining dress
