NEW Yellow/Purple Gown with Embellishments, Never Worn

Ordered this dress from a site in Turkey that was recommended by a friend. The dress & its fabric are stunning (exceeded my expectations) but unfortunately it is WAY too big on me at the bust. I am an A cup and this is meant for (probably) at least a C. The fabric is gorgeous and flowy. The colors are bright. The dress is very long at 195cm (I am 5’11 and could have worn heels with it). Sad it doesn’t fit me because overall it’s stunning - my body just got lost in the dress. Size M
