Aicha Hockx sent me these pictures ages and ages ago, of this amazingly gorgeous modern dress she made that features a Watteau pleat at the back.
You *must* go check out her blog to see the posts she wrote about this dress: with more pictures (including the front, which has pockets!), with historical references, and where she explains it all very clearly!
This would quite possibly the world's best cocktail dress if executed in gold brocade. Actually, if you showed me this in gold brocade I would not be surprised if you also said "Look, it's Prada."
I love this so much. This is the dress I will wear after the time machine is perfected and I visit 2039. (I don't want to look like a hick.)
