Sorry for the sidewise view, but the full-on was a bit fuzzy. Go check out the auction for a better look. And do it in a hurry — this one ends Jan 3. I don't usually post things that are ending so soon, but this is B49/W37, in perfect shape, and the starting bid is $39.99. So go!
It's hard to find larger sizes in good condition; one theory is that they've always been so sparse on the ground that they get worn to death. The other is that, since they're larger, they get cut down into smaller garments. I'm sure there are other theories out there, some of which probably involve the old socks-and-the-dryer chestnut, but hey, if you put a dress like this in the dryer you deserve to have it disappear!
The dress is rayon, the buttons rhinestone, the dots heavy net. Really a stunner. Check out the other VintageTrend auctions while you're there; lots of good stuff!
