Lingerie shops in boston?

I'm looking for a place where I can buy lingerie in Boston. I'm not talking about French Maid costumes, or anything like that- think bustiers and corsets, stuff that's racy but still classy. I'm also not trying to spend a fortune- no more than $50 for a bra/corset would be ideal. I was thinking of going to condom world, on newbury street, but I'm afraid all the stuff in there would be too kinky. Any ideas? (And PLEASE don't say victoria's secret... They don't have what I'm looking for, I checked already.)
