Advice please?

My husband and I have been together 4 1/2 years. This might sound silly but I've never worn any "sexy lingerie" for him! He's told me that kind of thing doesn't really do anything for him, but I kinda want to do something special when we go away for a few days for our first wedding anniversary next month. Do you think that when he sees me in it that he'll change his mind? I don't want it to look like I'm trying to hard, or just look stupid either. Anyone have any thoughts/advice on this?!?!
