From Bras to Bag in 10 seconds

Ok! We already knew that Japanese people were not thinking exactly like the rest of the world (it makes them both loveable and totally foreign to us Westerners). But, this time, I admit they caught me by surprise with this major (?) technological innovation serving what is at the core of every woman in the world, but maybe more in Japan than elsewhere:

Bras that transform themselves into a handbag

The operation does not seem to complicated as can be seen below. It does not take more than 10 seconds. But it leaves me wondering about the real-life circumstances where the elegant Japanese lady would really appreciate the ability to move from one to the other.
