Black Mori Lee Grad/Prom Dress Size 6/Size 14 Bridal in Rocky View, Alberta for sale

I have a black Mori Lee dress from their VM collection. I bought it for $800, and decided to go with a different one but I can't return this one. It's brand new and has never been worn. I'm a size 6 in normal jeans, but this dress is marked as a size 14 because bridal wear is much smaller.
Features:
Assymetrical design with train at back
Hand sewn beading at top
3 layers on skirt to make it flare out
Snug fit at top and waist, flares out a bit at bum and legs
Zipper back, but I have been told it can be altered to bring it in tighter.
The dress is very form fitting, and makes your waist look tiny, I just have not had it altered to fit me properly.
I need this dress gone fast, so I'm open to other offers or reasonable trades.
