Very cute together, I think. I just wouldn't wear anything to elaborate or boho-y (if I may make up a word). I would stick with a simple cream sweater (if it's chilly enough) or basic girly top as Valencia suggested (I think the first one she posted would be better).

I could see it winterized with a turtleneck and tights or for right now with a feminine top. Just make sure you don't pair it with anything too rugged or it might look cowgirlish.
