Yeah, the two measurements are really not enough to fit all the different boob shapes. And just offering different shapes with the same two measurements leads to problems for those who otherwise could rely on the two alone.
I have that problem with trousers where one measurement for width is not enough to fit both my waist and my hips. With bras it's just that apparently you can't have more than B or at maximum C if your underbust is 28/30. According to companies at least.
I just realised that I'd never seen a picture of the whole composition before. Only of individual panels, especially of the central picture of course.
So you also taught me something new today, @perishthethought@lemm.ee
