I thought that I would wear a 4, but because it is looser at the hips, the 2 fit perfectly and was snug on the waist. It hugs your curves, which is great if you have them! The cons is that the bottom seems a little see through. However, this was minimal and did not show anything in pictures with flashes. Also, I had to use double stick tape for the bottom of the dress because it was so long (3 inch hem). The color is GREAT. What you see is what you get, the orange is actually that vibrant. The zipper was temperamental, even when the dress was on the hanger, and needed a few good tugs to get up and down. This dress was worth it though. I definitely recommend this dress, especially if you have a fuller bottom half and a narrow waist!
