Impossible bra search

[Tacomuseday]

Please help me. I need a bra that works with this neckline and doesn’t show straps. I’ve ruled out strapless as I get a ridge in my armpit fat and I’ve ruled out the wonder bra multiway bra (and similar designs for the same reason.
I tend to need a bit of padding for shape so can’t go braless, but using clips to bring the straps together distorts the shape of the cup.
does anyone have any good ideas please?

My DD wears this style a lot. She just wears nothing or a strapless style but then she’s thin/small chested. Maybe it’s just a style that only works for some body shapes?
Unhelpful sorry.

What about a racer-back sports bra?

Or a halter neck

Sorry I should have been clearer, the issue is the straps showing at the front not the back, I have loads of bras that cross at the back
