English mechanical engineer and professor John Tyrer from Loughborough University tackled the problem of bra design after his wife returned disheartened from a shopping trip when she could not find anything to suit her needs. On assignment from the British government, he uncovered that 80 % of women wear the wrong size of bra. This is because chest diameter and maximum breast diameter rather than the volume is measured, especially when the body is in motion. According to Tyrer, "to get the most supportive and fitted bra it's infinitely better if you know the volume of the breast and the size of the back.". He says the A, B, C, D cup measurement system is flawed. English mechanical engineer and professor John Tyrer says, "It's like measuring a motor car by the diameter of the gas cap." "The whole design is fundamentally flawed. It's an instrument of torture." Tyrer has developed a bra design with crossed straps in the back. These use the weight of one breast to lift the other using counterbalance. Standard designs constrict chest movement during breathing. One of the tools used in the development of Tyrer's design has been an projective differential shape body analyzer for 40 000 GBP.

Contrary to popular belief, breasts weigh up to ~1 kg and not ~0.2 .. 0.3 kg. The popular documentary TV show I Didn't Know That uncovered this information in a broadcast program. Tyrer said, "By measuring the diameter of the chest and breasts current measurements are supposed to tell you something about the size and volume of each breast, but in fact it doesn't". Bra companies remain reluctant to manufacture Tyrer's prototype, which is a front closing bra with more vertical orientation and adjustable cups.
