Kuja's Looks
Here I will describe Kuja's looks! I'll be using Amano's design sketch to do this!
[Amano's design sketch!]
Site note: in some fanfiction he is described that he looks like and angel. I think that describtion of suits his looks as well. ^_^

Face & Hair
Kuja has long silver/white hair, round the length of his lower back. However, not all his hair is the same length, it has been cut in layers. (you can see it a little on the picture). He also wears 3 feathers in his hair (although some say there are four). Several bangs cover his face sometimes. He has a pale skin, and blue eyes. He uses red eyeshadow on his eyelids. But I'm not sure if he puts something on his lips though...his face looks a little girlish...(not negative meant)

Kuja's Armour
Kuja's clothes are revealing. His armor only covers his chest and leaves the rest of it bare. His armor exists out of two or three purple plates on top of each other, each with a gold frame-like thing. Under the plates there's what seems like some gold-coloured fabric, tied around him with a silver belt. The purple armor continues on his shoulders untill his upper-arm part. On his shoulders are two plates wich seem to be made from metal. The rest of his arms are coverd with long white sleeves, wich are very wide. On the picture it seems like he has something like gloves in the same colour of his armor. He doesn't have them in the actual game, I personally think those are wrist bands instead.

rest of Kuja's clothes
This is quite a weird angle! ^_^ :P Anyway...now we get to Kuja's trademark; his thong! His thong probably serves the purpose of keeping his white hakama from falling down on the floor. The hakama is round the lengt of his enkles and probably serves to hide his (silver) tail. The thong is the same colour as his armor. Two stripes are on his hips and two a little lower, where the hakama is being held up. On the hakama there's a golden stripe to match the rest of his armor.

Kuja's legs
Kuja's legs and feet are hide away by tigh-high boots, wich are the same colour as his armor. If you look carefully, the boots have some different layers, and round the knees there's a part sticking out...(looks cool I think). On his feet there are buckles and something that looks like bat-wings on each site of the boot. The boots have small heals, and are a little pointy.
Allright, I think I had every part of his clothes. I might make Trance Kuja someday, I'm not sure though! I apolagize for any spelling/grammar mistakes or weird descriptions (wrong words).
