I like these shorts very much.  They are light weight, very comfortable and great for hot weather or a heated workout.  I like that they come below the navel, making it easier to bend for stretching.  Yes, they are loose, but I like them that way.  I have 35 1/2" hips, and the small fits me fine.  If I wanted them tigher, I could probably wear an extra small.  When I launder them, I put them in my mesh lingerie bag and machine wash in cold water. I've also washed them by hand in the sink. I hang dry them. (Note that any clothes last longer if your can avoid machine drying them.)

August 2013 update:  In the older shorts that I bought a year ago, I wore a small.  In the newer ones, I wear an X-small.  They seem to be making them looser now.  The startling orange is a neon orange -- very bright.  Not my first choice in a color, but I love the comfort of these shorts.
