I'm wanting some new bras. I was a 28G before I had DS. Grew slightly but not much during pregnancy, they went massive when I was breastfeeding, no idea what size as I didn't do it for long. I went for a fitting at John Lewises. Closest fit was a 30G but it was just slightly too tight on one boob (really slight) and the back was loose. They didn't have any 28s but the lady recommended a 28GG or 28H.
I'm not sure which size to order. I measure 28.5 underneath and 38 around the boobs. I don't want to order two sizes if I can help it
