Justina McCaffrey Wedding Dress Claire

Hello. I have a beautiful Justina McCaffrey dress that I wanted to wear but it is too small in the chest area.
Originally $2000. This has been worn once for an indoor wedding for a few hours, then cleaned and stored in an archive box. I tried it on once, so it needs to be pressed again, but is very clean and new.
The style is claire. It is made of heavy shantung silk with box pleats and pearls and embroidery around the waist. Spaghetti strap sleeves. It is a 10, but has been taken in around the chest and has had bra cups added. It fits more like an 8. Somewhere between an a line and a ballgown with a sweep train and pickups on the back of the skirt. It is really amazingly beautiful, and feels very luxurious.
I would like to sell it for 700, but please make an offer.
I can`t seem to post an image, but I have them if you`re interested.
