ASOS light pink size 2 halter bridesmaid dress

ASOS light pink floor length bridesmaid dress. Size 2. Only work once. Fitted along thigh area and then flares out slightly like a mermaid fit. Only alteration done to it was shortened - I’m 5”5 and wore 2” heels with it and it was just grazing the floor. Freshly dry cleaned. Missing top button in the halte neck section.
