I used a bone brooch to gather up the centre front of the collar, and am really pleased with much better the dress looked. Wearing the right underwear, accessories and make-up also helped me feel much happier with me+the dress. It's looser than I would like, but as it has no side fastening it needs to be able to go over my acreage of boobage.
Here's a quick post with a photo taken by Desir Brulant. I haven't even seen my own photos from the weekend.
