Hot pink A’gaci cocktail dress, Medium, fits Small

This hot pink satin cocktail dress has a pretty sweetheart neckline and flattering gathers in the front. It is strapless with elastic in the back for stretch. It zips and ties and has 2 comfy pockets in the front. 55% poly, 42% cotton, 3% spandex. It says medium but it must be a juniors, it fits more like a size 5 than a 6. I just received it yesterday and it doesn’t fit so hoping someone else can enjoy it!
