I'm the same size as you
(as we've already established!) and I find both M&S and Debenhams do some pretty nice bras in our size, not the widest selection in the world, but pretty and fit me well without having to pay Bravissimo prices.

I might have to go and have a proper look
because paying £30-£40 for a bra is outrageous

Yes! they do cost a lot which is a pain.
Another reason I always wanted smaller boobies.

yes
look at La Senza and Agent Provocatuer. All designed for small to medium breasts, and all pretty and lacy and nice

Just head for the DD+ ranges
I can't remember brand names off the top of my head, but there's a few in both now and are £15-£20 a bra and I'm quite a fan. You may have to hunt around a little though, but the last few times I've been I've come home with something and that's almost unheard of for me.

not the best-looking of bras, but not ugly and they're like tit scaffolding
