A real miracle bra!? The device consists of two plastic domes, a microprocessor-controlled vacuum pump, and a sports bra to hold it all in place. The pump applies gentle suction, no more than the difference in atmospheric pressure between street level and the top of a tall building. Worn for ten hours a day for ten weeks, it increased the size of women's breasts by an average of 100 cubic centimeters, or approximately one cup size. The bra that keeps on giving.
Vacuum bra: give your bust line a boost "If you suffer from cleavage envy but are averse to scalpels and sacks of saline or silicone, there’s a new option: Hoover-ing your way to a bigger bust with a battery-powered wearable vacuum bra. Physicians are lining up for the chance to offer the Brava Breast Enhancement and Shaping System to their less-endowed female patients." (see also Brava, the creator of the device)
