Apparently the bra reacts to changes in body temperature, supposedly due to sexual arousal and changes shape to push the breasts together, making them look bigger. When your body temp drops, so do the boobs and the bra adjusts cleavage accordingly.
Is it so hard to understand that body temperature does not rise only due to arousal?

Here's another bizarre one.. A Husband Hunting Bra specially created for Japan's singles market. The bra features a self set timer: "First you decide your target time or deadline until marriage and the countdown clock will start. Once you find your life partner and get engaged, you have to insert the engagement ring into the slot and the clock stops and The Wedding March begins."
Imagine wearing a ticking clock! How innovative and absolutely comfortable and of course not psycho at all. This is Triumph keeping abreast of Japan's singles market by making a specially-designed bra for women whose biological clocks are ticking.
Some companies have way too much time and money on their hands.
