Bras chafing middle of upper torso

Em

My bras, even sports bras and soft, low support maternity bras seem to be rubbing here and causing a rash?

Its right in the middle between my boobs and where my bras usually sit.

Its not painful, but it gets itchy and the red spots are kind of smooth and harder than the rest of my skin?

I've tried lotion and letting it breathe and it doesn't seem to be going away.

Anyone had anything like this? I don't have it anywhere else
