I'm short and depending on brand either a 6 petite or an 8 petite. Lately, more of an 8. Both the 6 and the 8 were too small. Well, the 8 was fitted. Probably how it's supposed to fit around the hips. The dress has a slight mermaid shape. It's very long, good for tall people or with high heels. Would definitely require hemming if I kept it. The sleeves were perfect, probably 3/4 for most people. They're bracelet length for me. The quality was surprisingly good, especially at the price.
