I'm currently wearing a 34D which is quite tight. I have measured my under-bust which is 31" and my bust (just before feeding so I should have been fullest at that point) which was nearly 39".
What does that work out as?
I have a budget of only about £30 and I need to buy from somewhere like M&S, Debs, House of Fraser. We don't have any of the bigger underwear stores in my town.
DS is one week old today if that is relevant.
