Check out the drow spider silk armor in the recent drow issue of Dragon. (cant recall exactly what issue number, but I'm sure soemone on the boards could tell you). It has a +3 armor bonus and a very high max dex, in addition it only has a 5% arcane failure. Really ggod stuff from high dex fighters, rogues and fighter/mages.
I have a high dex character and I've gone through looking for the same thing. Basically, the answer is "no, you can't really wear armor". Go with bracers of armor.
There's the armor of the celestial batallion in the epic level handbook, which is really nice armor but out of the reach of almost everyone. I'd wear it if I had it, but I'm not going out to mug a solar to get it.
I've analyzed various combinations of armor, special materials, enhancements, and so on. Unless you go with some kind of non-standard enchantment that lets you raise the max dex on the armor (something WotC has so specifically avoided that I must assume it's by design) you are better off just going with bracers of armor. As a side benefit, they're reasonably common items in most campaigns so you can find bad guys wearing them.
