Try "adore me" it is a website that seems to have some really cute stuff - haven't tried them, so I don't know about their quality, but they seem to be cheap and geared primarily to the cute, young things:)
I agree, the good stuff is expensive. Unless it is on sale and I can try it on, I don't buy it. I tend to buy my unmentionables when I'm on vacation visiting family and friends in Europe - dirt cheap in comparison, unless you insist on top french design ...
Not originally something that I would have considered bringing back as a souvenir, you understand:), but it has saved me a good deal of money and I enjoy having a nice, big selection of fancy, lacy bras that actually fit well and wash well, not to mention they do look sexy.
My DIL did something similar on vacation in NYC, visiting an outlet that specialized in fancy underthings. I bet right now is not a good time to purchase with Valentines Day on the horizon - a Visa card to be used after V-day, presented with a red rose might be a better idea.
