I think most women struggle with finding a comfortable, good fitting bra. Our younger daughter is tiny, an XS or "0" clothing, and she has problems just as I do at the other end of the scale.
No how, no way am I wearing underwires. When I find something that sort of works, if it has underwires, I make a snip in the casing and rip it out.
As I've aged, my skin has become very sensitive to anything that is not cotton or linen. I can't go without a bra as the skin under my breast chafes. The struggle is real
I've been eyeing Miss Mary of Sweden bras online. Not available anywhere locally. They are quite pricey, but if they are comfortable, it would be worth it.
