I have the same problem! Also, when I manage to find a bra my size, it's all about minimizing and "full coverage". Look, I like my boobs. They're nice, I get along with them, I don't want to minimize them, people pay for this these things and I got 'em for free, I'm all about showing off a bargain! And those "full coverage" bras don't stay hidden under my v-necks, because yes, girls with big boobs do actually like showing them off a bit from time to time.
Meanwhile my small chested friends complain about however everything is super padded and push ups. Apparently if you have big ones, you want small ones, if you have small ones, you want big ones, and designers have decided no woman is happy with her body. Lovely of them to make that decision for us.
Yep, the retailers seems to think that I should be ashamed of my A/B cup. There's a fairly nice brand that is not too expensive and ok quality that has a line called Glam, that line has 10 different bra models, only 2 are non padded. The rest is either "push-up" "double push-up", "magic up", "plonging magic up", "the maxi(mizer)", ...
(and I'm not making those name up)
And both the non-padded ones are made with lace, I don't know how they do for headlights (not a problem for me tho), and start with B cup
I usualy go for non-padded but still a somewhat rigid cloth cup, not in this brand anymore.
And you usually either get very basic/ plain color ones, or the cutesy ones with Hello Kitty or Winnie the Poo
And they're adult bra, you can get a heavily padded hello kitty if that's what you want, but seldom a sexy/grown-up non-padded one.
