I purchased a custom gown from Emma & Grace Bridal in Denver, CO.
Top... Emma & Grace Private Label/Custom beaded, cap sleeve bodysuit. (paid $3,200, asking $1,500)
Slips on over the head, and clips at the bottom. Could wear with any other skirt. Has a beautiful low front and back, but is all covered with sheer, so it doesn't feel uncomfortable or 'too open', and the sleeves won't move around.
The beaded top was altered to be a little bit tighter, so that I wasn't self-conscious about it moving around or having gaps. They kept the fabric in tact, so it could always be let out if needed.
Skirt... Alexandra Grecco chiffon skirt (paid $1,500, asking $300)
I had the skirt altered to fit my height (5'5"), and it has a small amount of staining at the bottom, since my wedding was outdoors (it is extremely faint, not at all noticeable.)

Will consider selling the bodysuit and skirt separately, if you are only interested in one of the two.
Please let me know if you have any questions!
