Some designers do care and start their lingerie business, often out of their own needs.

Britain’s getting bustier. The average UK bra size is now a 36DD (compared with 34B 11 years ago) and 53% of cupped bra sales at Selfridges are now 34DD or larger.
It can cause stress and feelings of unworthiness if you think less of yourself because of the proportions you have. Read more about the average UK bra size

Why an average is just an average?
If I was a lingerie manufacturer I sure would want to know about the most common bra sizes.
But are the researches done right?
I think not.
- researchers never mention cup AAA and most miss cup AA as well
- a lot of petite never enter a lingerie store feeling they don’t belong there
- which indeed we do not, because our cup size isn’t being sold
- I know many petite women still wear a too-big cup AA, A, or cup B
