Sports bras that fit sizes above DD

Does anyone knows a Uk brand that make sports bras by cup? Most I see are by general size (S M L). An L is too tight on my chest (G cup) and if I size even more up it fits weird on my back/armpit.

Most brands I saw were over 50£.

I don’t get why do women’s clothing don’t understand women’s body. We come in all sizes and shapes. It’s so frustrating that I’m always punished for having a bigger chest.
