In the spirit of dreamy generosity, throughout December, we'll offer one fabulous, crave-worthy gift idea each day. And what better way to begin than with the dress coveted 'round the world?

We're kicking things off with the (appropriately) royal blue, long-sleeved, silk jersey Issa dress that Kate Middleton wore while announcing her engagement to Prince William. It's $535 at net-a-porter.com. (And it's already sold out, but you can grab a spot on the waiting list should more become available... or check out some other looks from the princess-to-be's favorite designer.)
