I ordered a size 2, which is a true size 2. If you are broad shouldered, maybe opt or the size 4. The quality is very high, it sparkles beautifully. The slit is high, but still classy and sophisticated. The dress gives a modern take on Old Hollywood. It feels like something Marilyn Monroe would have worn. I love the structure the dress has. It has boning in the bodice, which gives me a snatched look in the waist and it glides nicely over the hips and butt. It's so fabulous I am obsessed.
