The world's biggest bra (pictured being hung from the ITV Tower in London) is currently being auctioned off on ebay for a breast cancer charity.

The Mega 1,360B bra is as big as two tennis courts and weighs as much as 1,800 traditional bra's. The auction of the world record bra is being held to raise money for breast cancer awareness.

The starting bid on the ebay auction is about $800 US dollars. The winner of the auction will also receive documentation from Guinness World Records stating that the bra is the world's largest. The auction continues until October 28th.

Not sure what you would do with this bra if you won it, but it's definitely a conversation starter if you hang it in the man cave.
