Change armor styles
There are plenty of different armor styles laying around, you just have to know where to look.

There’s over 30 different armor sets for each armor type (light, medium, heavy). When you take into account that you can purchase higher level armor from the Trading Post and transmutate the looks into your lower-level stuff, you can mix and match the looks of your armor set quite broadly.
Here’s all the medium sets available (except for the Cultural armor sets available to races other than human): http://img715.imageshack.us/img715/4994/mediumarmorwithnamesfin.jpg
