There are some more good tips, thanks everybody. Here's something funny. I can't find cargo shorts in stores because of the winter season. So, I was going to buy inexpensive cargo pants from Costco, cut them into shorts and then seam the bottoms for neatness. Now, I'm thinking I won't seam the bottoms so that I intentionally look raggedy and poor.
Hit your local used clothing store. They usually have lots of out of season stuff.
