I don't usually do this, but I came across something this weekend that was too good to turn away from. Wandering through the Neiman Marcus outlet this weekend (research!) I stumbled across this:
The velvet is rayon, the lining is silk. There's a zip up the back. The dress is very hourglass-shaped -- McQueen cuts for women with some backside, god bless him. But the genius of this thing is how alterable it is. There are four vertical darts across the front and two on the back, all of which would be easy to adjust, and the zip is in the center so the side seams can be taken in. There's no slit or kick pleat at the bottom of the dress, so it could be hemmed as much or as little as required with no trouble. It's very, very customize-able -- decent tailor will be able to make this thing look like it was made for you.
The one up for grabs is a size 46. Mine is a 42, and based on how the 46 fits me, I'd say it translates to about a size 10. Using my personal measurements and a tape measure on the dress, I think there's room in the skirt for up to 41 - 42" hips and a 30 - 31" waist, and up top I think it would definitely fit someone up to a 34C, possibly a 36C. Like I said, it's hourglass-y: 32A me has a big ol' padded strapless bra on to fill it out, but the cowl at the neck makes the fit of the bust a little more forgiving. The center back seam from the top of the zip measures 38", and there's a good extra inch on the hem to be let down if necessary.
So. There you have it. If you're interested in the dress, send me an e-mail & we'll chat about it. The $150 includes postage. If you think it would work but are unsure about the fit, we can discuss the possibility of returns, but there's a time limit, so act fast!
