Im the exact same hun, I got offered 250, 275 and 300 so I said 300 and no less! Haha I got told a 300cc high profile would make me a full C at least, but should be a D because ive got such a tiny waist, ive got a pic where I tried on the 300cc sizers but they look a bit saggy cause im flat chested and the sports bra was too big so didnt hold the sizers up very well. 🙂 xx
