Where to find orange golf pants?

I'm playing in a charity golf tournament in a week, and I thought it would be fun to dress up like Rickie Fowler. I have the orange shirt from my school uniform, an orange belt, an orange Puma hat, and orange golf shoes. All I need are the orange pants. I have orange jeans but I can't wear them for the tournament, and I've tried the golf smith website but found nothing. Where are some other places that I could try? Thanks for the help!
