It seems that this glowing bra is made in commemoration of the tenth anniversary of Playtex 's "Moonwalk" event.


Moonwalk is a charity marathon running through London with a brassiere decorated gorgeously by many women, and the collected money seems to be donated to the charity project of breast cancer.


The amount of money Moonwalk collected last year seems to be 4.6 million pounds (about 1.1 billion yen), but the organizer is aiming for more.
