This look is so throwback Posh!

Victoria Beckham caught a flight back to London out of L.A. yesterday to meet up with the rest of her family, and the fashion designer wowed in a plunging neckline tuxedo jacket. She would not have been able to pull this off if she hadn't had her breast implants removed!

The former Spice Girl just celebrated her 41st birthday in LaLa land, but getting older isn't slowing her down! VB launched her collection at Barneys and shot a photoshoot while she was in town, but she had to head back to England because her boys are starting school again.

Zig-a-zig up and away!
