Peach Blush Sequined girls dress

This listing is for a peach or blush colored sequined girls dress. It is in great condition and has only been worn once for pictures. It photographs amazingly. It is by PS couture. It says it is a size 12 but I think it runs small and it fit her or like a 10. She is almost 12 now and it doesn’t not fit and she is average height and weight.
