My friend was committed, but it helped that it was not uncommon for larger endowed teens where I grew up. Doctors openly discussed the option and it was covered by government health insurance.
I can sympathize with the difficulty of finding the right size. It wasn't until my wife traveled to her country of ancestry and measured at a department store in her 20s that she finally obtained her first bras that truly fit. They still weren't cheap. I think that is when I learned the burden of what is, for most, a medical support garment.
And that is what I find so frustrating. Bras should be treated like a medical device: basic models that fit well should be covered by government health care. The 200-400% markup in most prices is outrageous, and there would be a positive return for society with women more confident in more activities.
Of course, I live in the United States, so we've regressed to the point of figuring out whether dying of communicable diseases is bad.
