I'm a 12 but I ordered an XL (14-16) because this is chiffon and doesn't have stretch. It's a little loose but it still fits well and looks nice. The quality is great. It's light weight and perfect for summer but not at all see-through. The chest cut-outs are cute but still modest (no cleavage or chest shows). I'm 5'9" and it hits me right around the knees. I'm in my 20s and like to have a variety of more revealing and modest dresses so this is a great addition to my collection and appropriate for many occasions.
