Bras cut into my back and armpits..

I don't know if this is the right place to put this question, I was having a hard time finding a place where I can talk about bras platonically lol.

I don't like wearing bras due to sensory issues. I don't like the clasp in the front or the back because it digs and I don't like the band around the back.

I have a smaller chest but I wide ribage and a muscularly developed upper body. I cannot find a bra (bralette or cupped) that doesn't dig into the fronts of my armpits or around the back underneath my shoulder blade. I can't usually get away with wearing something like the Free people Happiness Run tank as a bra but that doesn't work if I want to wear a lower cut shirt.

I measure as a 32C or sister size a 34B but digging and sliding up are issues.
