Where to find an odd bra size

Ivey • Married 6/11/2016 ❤️ Childless Not By Choice 🌸 Mom of Fur Babies 🐶🐱

I just had the correct measurements done after wearing a 32C for years and these bras always feeling loose. I always have to start wearing them on the tightest hooks. Well, I’m actually a 28C and I’m not sure where to find that size. 🙄

Any help would be nice!
