Birdwells are the standard but they're definitely anti-fit. The great thing about them is that they're pretty much customizable and you won't see yourself coming and going.
I like the ones from Saturdays; not sure who makes them. Also Katin has made some shorter ones. I know that Quiksilver
has reissued some of the 80s style nut-huggers, too.
I surf so I can't comment on nonfunctional brands. I go for a 21" outseam length, but that's purely a function decision.
