Prom/bridesmaid Dress. Robe De Bal/demoiselle d’honneur

Dress is size 6 but made very small. I usually wear 4 in normal women’s vest. I could even wear xs dresses at stores like Zara. I bought it online on the ABC fashion website and the brand is Cinderella Divine. Colour is terracotta (sienna). https://www.abcfashion.net/products/corset-cowl-satin-gown-by-cinderella-divine-7483?variant=42685807395067 I also got it shortened a bit because I’m 5,5 and was wearing it with average height heels.
