Why is there no decent werewolf costumes?

I've always wondered the same thing. I haven't seen any werewolf costumes. I've only seen wolfman, which suck. I know you can have them specially made exactly the way you want it by a costume designer, but it costs a lot of money. Other than that, you probably won't find one. Werewolves are really cool and the best Halloween costume idea, but for some reason they don't make them. :(
