Thank the lord for eBay. You can just about find everything on there! Like today, where I went searching for something else and stumbled upon the Bebe dress worn by Sophie to the Aston Martin bash couple of months ago.
There are a couple of listings on eBay for the same dress so you get to pick and choose! ;)
P.S Thanks to “Epiphany” (who as anonymous) pointed out that this was a Bebe dress way before!
