Hi Jade, I am 5 foot and 48kg, size 6/8. I was a 32A or a very padded 32B pre op. I am almost 4 weeks post op after 250cc round unders, not been measured yet but I expect I will likely be a c cup. I think mine feel a good size for me, I don’t think from a width point of view i coulda fitted anything bigger in than what i have. I am guessing that 350 would have you bigger than a C cup.
