Lydia Sylvestry's Infinite Dress, the dress you can wear 100 different ways. Actually there's a couple of brand names now including Butter by Nadia, one by American Apparel, Rachel Pally's Mexico dress, and a version by VS.
I think it's great for adapting to weight changes. I bought it for those events I need to find a dress for in a pinch and people will never know it's the same dress
And I love that there's a style that covers the upper arms. It's a bit $$$ but I bought one off of ebay for $20!
For the crafty people here, there's a link below for a do it yourself version

I'd get one if the skirt part of the dress was in a different style..
