Bra/Shopping Bag

Pink Tentacle brings us this crazy invention:

Lingerie manufacturer Triumph International Japan has unveiled a new type of brassiere that can be converted into a shopping bag. Called the “No! Shopping Bag Bra” (NO! reji-bukuro bra), the environmentally-friendly lingerie is designed to promote the reduction of plastic bag consumption, a key objective of the revised Containers and Packaging Recycling Law hammered out by Japanese lawmakers in June.
When the bra is being worn, the “shopping bag” portions are folded away inside the bra cups, where they serves as extra padding. The bra quickly converts to a shopping bag by removing the bag portions from the cups and connecting the hooks on the bra’s underwire. The lace cups serve as decoration along with the shoulder straps, which are disconnected and tied to the top of the bag as ribbons.

What is the purpose of this contraption? It seems about as useless as Mel Gibson at a Hadassah fundraiser. Sure it provides extra padding for the cleavage challenged (a problem I definitely do not have, in case you're wondering). But wouldn't you defeat the purpose if you whipped your bra off at the supermarket checkout, turning it into a shopping bag for some real melons, and revealing your own tiny you know whats? Or perhaps you wear a bra because age and gravity have created a whole lot of downward mobility. When you convert your undergarment to a shopping bag you're left with your own empty shopping bags hanging off your chest. The bra/shopping bag rivals these for sheer uselessness.
