I have been wearing 40F. The band is a little too snug on the loosest set, and it’s better than most bras I’ve tried, but not great. I tried to do the manual calculations, and I think it would be 42G. I got a little overwhelmed, so I’d love if someone could double check my math and help me out.

Thanks!! 💕
