Was this the first time you logged into frontiers? If so, stuff changed may look different from before you were on frontiers. One neat thing about frontiers though, is that now you can change the appearance of your char. Every time you log in, you go to server screen first, then pick a char, then you have an option to enter world or change appearance, so if you don't like your char's new look, hopefully you can find something else you like.
If you didn't just switch to frontiers then I have no idea and that's very wierd.
Don't feel bad, your not alone, there are a lot of people who were not happy with high level stuff like robes and armor (that they may have paid a lot of money for, especially the cv I heard looks really bad). I was only level 31 I think at the time, and was wearing dun plate armor, and I think that looked a lot better after frontiers.
Hope this helped, GL.
