Soul Calibur 1P: Xianghua's first player outfit is one I personally don't take a liking to, but it's still very cute. It seems like her outfit connects entirely from her pants to her top; There are designs of little moons and stars on the sides of her pants, and unseen to the photo above, there are small ribbons that tie the ends of her pants. There are littleintricate designs on her top lined with gold and blue. Gold and blue seem to be the main theme of this costume.
Soul Calibur 2P: Slightly cuter than the first player outfit. It looks alot like a chinese top of her time period (1500), and this time the intricate designs on her shirt are various flowers and green swirls like "vines". The colors of this outfit are darkish red and maroon with thrown in green for the flowers. Shorts make this outfit way cute :)
Soul Calibur 3P: The 3P has got to be the cutest outfit any Soul Calibur girl could ever wear. It's very simplistic in every sense, but the jacket's intricate butterfly design in the back is what makes this outfit stand out. The outfit seems to be lightweight. Her jacket is lined with flowers and red-orange gradients for the lining, as well as some blue thrown in the ends of her shorts and sleeves.

Soul Calibur 2 1P: My favorite one of them all, the sky blue princess-like outfit. This one looks alot more chinese than the last three from Soul Calibur, in fact, this one probably looks the most accurate to the culture. It's a tight-fitting outfit which has some traits from her SC outfit such as the blue pants (but now it's in two layers?) and the detailed gold lining of her pants. I like this outfit alot because blue and gold make a really beautiful match.
Soul Calibur 2 2P: This one is also slightly similar to the outfit she had in SC as her 2P. It shows quite a bit of cleavage at the top, and there'a strange broken pant leg on her right leg.. but the design makes it much cooler than it sounds. Again, the colors are the same as her Soul Calibur 2P but there's a slight difference in the greens, it's dark turquoise this time.
Soul Calibur 2 3P: Simple and looks alot more sophisitcated. Maybe it's the black and stockings? This one seems to have both colors of gold and silver, as well as black and white. She sort of looks ying-yangish. Again, there are flowers embroided on her outfit (when are they not?) and her hair seems to look different in this one too. It looks like there's a bun or a clip holding her hair up.

Soul Calibur 3 1P: Out of all the outfits, I think this one looks quite mismatched in colors. Pink and light green looks sort of strange together, but I think the shirt is very nice. It's not as detailed as her previous outfits, but I guess the color "match" makes up for it? Namco likes putting Xianghua in capri pants, don't they? She seems to have new headgear too, with flowy little ribbons of blue. Namco got rid of her detailed designs in her outfit :( Makes me sad.
Soul Calibur 3 2P: So, Namco decided to recycle the black and white ying-yangish Xianghua look. It looks alot more grey and white to me sometimes. Again, there are golden flowers and a huge hair clip holding her hair up. You can't see it from that image I gave, but her sleeves and stockings have petal-puff looking ends and it's really strange looking.. but nice, I guess.
