Kate Middleton wore a blue version of this dress to some event. I absolutely LOVE it. I would have worn it too, but wasn't able to get it altered in time. Shucks. My loss could be your gain.
This was purchased new (online knock-off... this is not a real Jenny Packham dress), is unaltered and, aside from twice in my bedroom, has never been worn. Keep that in mind, as the pictures don't do it justice and the dress will fit you better once altered for your body.
I took off $100 from my original price to recoup some of the money I spent. Make an offer.
