Plus Size Chantilly Lace Wedding Dress

Size 20 (might be closer to 18, not really sure) strapless Justin Alexander lace ballgown wedding dress. It fit when I bought it a year ago, now it's too small. (First photo is when I bought it, others are from most recent fitting.) I bought it from Brides For A Cause, so it was worn at least once before & I tried it on a few times. I had the corset taken in a bit and a sparkly belt added, nothing has ever been taken off the train or hemmed as far as I'm aware. We also put in a temporary bustle, didn't get around to finishing it since it didn't fit too well. There are 3 elastic straps and cups in the corset/bodice for support and it has both a zipper and button closures. I'm about 5'6" and in the 2nd - 4th photos I'm only wearing regular Birkenstocks, for reference. Last 3 photos are of the skirt, 2 prior are an optional shrug. No visible damage to the lace, no stains, no dirt; really is in great condition! It really is gorgeous, I wish I could've made it work. Also comes with custom- made lace shoulder shrug if you'd like :) Open to any offers!! I'd love to get this out of my apartment :)
