So I did the rounds of the bra measurement sites according to them I’m a 16D/36D. Which would explain why the 18B is a little uncomfortable around the cup area.

And continuing the theme of too much information, I am stunned that I could go from a 12B being roomy to an 18B being rather tight in 12 months! Its very unnerving suddenly having breasts and cleavage (and nothing comfortable to stuff them into).
