London ladies show off cleavage in national breast fest

Big Ben just got a little bigger. Women in London are taking to the streets in their bras and panties for National Cleavage Day, an annual celebration created by Wonderbra to help make women feel "feminine" and "sexy." Apparently it's a big double-D-deal across the pond. There's a Wonderbra Cleavage Hall of Fame that features top celebrity-cleavage picks (Katy Perry, Kim Kardashian and Beyonce rank high on the list), and British retailers such as Ann Summers promote their own wares by sending scantily clad women out into the London wild. Settle down, lads.

Naturally, a flurry of male boobs are trying to get other Tweeps to post Twitpics of the festivities. Breast of luck with that, fellas.
