What’s the biggest bra size you can imagine? Now take that number and multiply it by forty. The biggest bra ever, according to the Guinness Book of World Records is about a 1360B size and it’s hanging off a building in Londan right now.

The bra was part of the ‘Wear it Pink’ Breast Cancer Awareness Campaign and fundraiser. It is made from lightweight spinnaker nylon and weighs approximately 165 pounds. It spans the equivalent of 26 parking spaces and took four weeks to make. It was made entirely by a single person from M Putt Sailmakers, the only remaining sailmaker company left in London.

A chest that size would probably cause terrible back problems, so it’ actually hung from the ITV Southbank building in London as of October 28th. Technically, it’s the scale equivalent of a 34B cup.
