I like N. Hoolywood a lot, though I don't own any pieces. OC has a good stock this season. There were a bunch of things I wanted last time I was in there, especially these black summer weight pants. In addition to the others mentioned, I believe Park&Bond also carries them.
Anyone know of any companies who make reasonably cheap shorts, which end around mid quad. Like 7ish inch inseams. Not really fussed about fabric or quality. Wearing cut off sweat pants and they look a bit shit.
