Are you looking specifically for knights, more plausibly-historical, or just anything that's French-feeling? The more historical you're going for, the less likely I am to have saved it as I have a ton of costuming books if I need something historical, but I can help you out if you just want a French flavor to it.
Also, taking a break for a bit. It's late and I've neither eaten nor taken cold meds. (Inb4 I fuck shit up later while medicated.)
