Posh Frocks for a Princess-to-Be

Call it the "Kate effect." When the princess-to-be dons a dress, designers see their frocks fly off the racks. From her royal blue Issa, still on back order, to the white Reiss design worn in her formal engagement photo with Prince William, the Middleton effect is worth millions in free marketing.

Former Spice Girl turned designer Victoria Beckham is in Kate's crosshairs right now...and she's thrilled about it! She confessed to the Telegraph that "It's tremendously exciting and I would be honored if she were to wear my designs." Beckham added: "Apparently, she likes my clothes and has asked to see a selection. It will be from my current spring/summer collection." The designer characterized her spring/summer line as "all about shape and curves" when she revealed 26 looks last fall.

Beckham debuted her new fall/winter collection at New York Fashion Week. She showed 29 pieces -- view them here and make your fashion prediction for what Princess Kate will wear this autumn.
