Well, I buy a lot at a place called Jacob, but I think it's only in Canada. Maybe they have a website? But they make super cute stuff, most of which is ultra low rise so you can wear them with low cut jeans. They're comfortable but sexy....some have tiny lace trim or tie-sides, ribbon, fine mesh, awesome colors. Even the 'comfy cottons' are sexy.
Hands down the best I've ever come across.
