Great, so now I know I'm a 30dd, not a 34a. That's all well and good if I could actually buy bras in this size! Went into house of Frazer, nothing under 32. Went into m&s, a couple of options, picked up a 2 pack of t-shirt bras, not perfect but will do for now. Picked up 1 bra in tk maxx (the only one in my new size but it fit and was only £3). So now I refuse to wear my old, ill-fitting bras, I have a couple of new, ok-ish fitting bras and am clearly going to have to travel further afield or risk ordering online for all bras in the future! I was blissfully ignorant and slightly uncomfortable until 2 days ago, now I'm empowered and cross!
