Might want to look into finding some athletic stretch material since that generally tends to look pretty smooth and doesn't wrinkle that much when in use. Or find some grey shorts/pants/whatever that look similar at a [sports] store that sells athletic-type clothing then just modify it to your needs.
Ohh, thank you for clearing that up!! That's a really simple way to do it! ~
