New to this, but been playing for awhile etc..

I pass people all the time and take a look at what level they are etc, and noticed today that I've seen a few with the armor names rotating, it may look like one, but then flips (the name) to another..

How can I do this? it was on a lvl 30 char, was wearing the one vest that I liked for my char but also wearing a higher rated armor but showing the other... sorry if I confuse, I'm confused my self...

loving it so far, need to get some more xp 180k a level is nuts hehe,
also found out I need to learn a few trade skills (craft/leather etc) but not sure what to start with.. any tips would be great...

and whats the name of the shiny white bow that glows? Id like to get my hands on one
