Spherical segmental technology?

I can remember when a Mystère was a jet fighter. Nowadays? The Guardian reports:

According to the makers of Le Mystère's new No 9 range, the fashion for "fake look" implants has given rise to breasts that are too round, too high and too pneumatic for conventional bras. "The trend has been to use higher-profile breast implants with a narrower base and more projection, which means that traditional bras tend not to fit properly," explains Dr David Brothers, the Atlanta-based plastic surgeon behind the range. "Even normal straps and material aren't ideal."
The No 9 bras respond with a "mathematically defined and designed cup", using something called "spherical segmental technology". All this engineering comes at a price: Harrods are stocking the range, which starts at £60.
