Revelry bridesmaid dress size 20

I wear a size 16 Jean the size of this dress ended up being a 20. It is normal that it is size up from what the website explained. The mustard color on the velvet fabric really looks more like a gold. The petite link was perfect with 4 inch heels on my 5’3“ height. Color: Mustard-603 Style: Gwen Size: 20 Length: petite-41" waist to hem Material: velvet
