Buy one or two for her, put them in a cute box, and give it to her. Tell her, "I'd love to see you in these" - or something, and see how she responds.
Girls love to feel sexy, and I think that her knowing you want to see her in sexy lingerie will make her feel more desirable, too.
maybe buy one for her, and tell her you thought about her when you saw it, because she has such a nice body and that would turn you on for sure. (or something along those lines ;))
Buy her one for a gift and ask her to wear it for you at intimate times because it's a turn on for you.
By taking no for an answer, if that is what she says.
Have you even bothered to ask her yet?
"Would you mind wearing a g-string once in a while?"
