This is a nice dress. The adjustment on the shoulder straps slip a bit as you wear it. I had to sew them in place, to stop the dress from showing more and more cleavage as the day goes on. Probably only an issue for those with larger chests and it is an easy fix. There is a pull string adjustment running down the front of the bodice to allow you to adjust the top for a wide range of chest sizes. That allows you to choose not only your size, but your modesty level as well. I've never seen this feature before and I have to say, I like it. It really does allow for a custom fit over the chest. Sizes A-D should fit this dress comfortably.
