Absolutely beautiful dress. I tried this on and compared it to about 10 other dresses in the store. It's worth paying a little extra money to get the quality of the dress.
Just realize that there is a good chance you will have to get the bottom hemmed, even if you wear heels. I am 5'6", ordered a size 6, and had to get 6 inches taken off of the bottom. Also, I had to get the halter around the neck a little bit shorter.
Otherwise, it's a very comfy dress that looks stunning. As a flat chested individual, sometimes it is hard to find a bridesmaid dress that looks flattering. This one did the trick for me.
