Remember the first time I excitedly reported this site (http://www.mylineage2.com)? :D
:( Right, probably not.
Either way, it has a fashion preview tool containing most sets you might find yourself wearing (it's fairly complete from C Grade and up) over extended amounts of time, featuring a back and a front view in higher resolution than the official tool (http://boards.lineage2.com/showflat.php?Number=541493).
It also has some other features, but I'm too lazy to pseudo-translate that. :p
In fact, I now do not have a translation, but simply a guide of what is where.
To navigate the site, watch the status bar (bottom left of the browser window - it should currently say "Done". When you mose over the "Reply" button to this post, it should change to something rather lengthy looking a bit like this:
http://boards.lineage2.com/newreply.php?Cat=&Board=shots&Number=....
The links on mylineage2.com are fortunately in full English, meaning if you watch your status bar, you will be able to navigate the site easily without ever having to know a word of Chinese.
Here (http://img116.imageshack.us/img116/5617/mylin24ho.jpg) is a picture illustrating the layout of the site. Simply click first in the top box, then the bottom will appear - then mouse-over until you find the race you're looking for.
Note that classes that do not have a unique mesh for a given armour are not listed, meaning you won't be able to find pictures of fighters in "robes".
To access the fashion preview tool (http://www.mylineage2.com/fashion.php), select "armor" and then follow the guide above.
