Pink Floral Medium Dress

Beautiful floral pink dress! No brand. Bought secondhand but unfortunately is way too big in my chest! Seller said like a size small/medium. I’d say it’s a medium, not good for smaller bust. I’m an A cup and it was almost falling off :/. I’m about a 30-32 inch bust. 28-29 inch waist. It fit everywhere else but my chest! Pic of me wearing at end, only tried on!
