H&M rose print button down tea dress size 4 or 6

Preloved from H&M. Fit and flare tea dress in black and pink rose print. Black buttons down the front. Material is a sheer chiffon with black lining. It's too tight at the bust for me, otherwise I would keep it! For reference I'm usually a US 2 and H&M 6. I think this would fit a size US 0 well. My stats:: 5'2" 32C-26"-36"
