Bras with wide sides

I’m 7 was post lumpectomy and I’ve been wearing Sainsburys front fastening sports bras. These are fine but because they are sports bras they are very deep from cup to where the sit on my tummy. I find by the end of the day I feel constricted around my middle.

I bought a non wired bra from M & S but the side rubs right on my scar. I’ve tried my old bras (underwired) but these too rub my scar. 

So I’m on the hunt for normal back fastening bras with deep sides. Why is nothing ever simple?

Forgot to say, I’m also only a 38C so not big busted which makes things trickier as most bras seem to be for ladies with larger boobs.
