I agree with everyone - do not have any future conversation about what underwear you have on. IF she knows, she probably doesn't want to talk about it. (Think "awkward & creepy"). You may be overthinking this because it sounds like you would like someone to know.
As Dutchess pointed out, if you want hints from a GG or any other CDer support, ask your wife.
By the way, most GG's past the teen years don't "talk make-up hints" unless they are selling it at a makeup counter.
