Armor

Sophitia's base outfit for soul edge is a lovely little number. Her hair is worn down, with short bangs that mostly cover up what appears to be a golden Sailormoon-esque tiara with a few green gems in the center. Sophitia's eyes are green in this style (though they appear as amber/yellow in Soul Calibur II) and she actually appears older in this game than in Soul Calibur (however that's a given considering the leap in 3D imaging abilities between the release of the two games). She sports a pair of metallic shoulder pads and a leather choker that holds up a pair of leather straps, which in turn hold up her silver breastplate. The breastplate is mostly leather, with a bit of metal covering the breast. She wears a pair of golden wristbands and a pleated white skirt. Her shoes are--no surprise here--greecian style sandals with reinforced toes. This style also appears in several other fashions...
you can have her in brunette.                 She's also pretty in pink :)

Sophitia's Soul Calibur armor isn't a very drastic leap from the main armor of her Soul Edge days. However, unlike in Soul Edge, the only color coated thing about her is her panties--that's right boys, our favorite Rainbow-licious Greek Goddess' panties change in this game! Sadly, you can't customize armor color this time.
Sophitia's hair is not worn loose. In Soul Calibur, her hair is worn in a messy braid; hair falls around her face and into her eyes--which are amber-colored in this game. She replaces her blue breastplate with a blue cloth shirt that laces up the front (to provide real-time boobie-wiggling action for the male fans--even I noticed that). The loose top is buckled up at the shoulders by silver buckles and a pair of leather straps. Her all metal shoulder pads are replaced with shiny blue shoulder pads over-top of white cloth. Sophitia wears a fancy belt and pleated white skirt (this one has a fancy blue design around the hem). She's traded in her Grecian sandals for a pair of reinforced thigh-high boots that probably offer more protection than her prior strappy sandals.
Sophitia's second Soul Calibur outfit (and my personal LEAST favorite) features a white and blue tunic (with nothing underneath, obviously), a pair of silver shoulder pads with pink fabric guards, and a pair of white gloves. At the waist, Sophitia wears a hot pink skirt that completely reveals her left leg, but obscures her other leg to the shin. This skirt is held in place by a black leather belt/strap wrapped around her waist twice. Sophitia wears a pair of complex pink and brown boots, and thick white socks that come up to the thigh and are held in place by lots of pink strap.
In this version, Sophitia wears her hair down, and she also has a bizarre leather belt strapped across her chest. Her eyes are yellow in this version as well as in the first version.
Sophitia's main costume in Soul Calibur II is essentially identical to her outfit from Soul Calibur. This is not unusual, as many of the returning characters have secondary (or primary) outfits that are identical to, or slightly modified versions of, their original costumes. The major differences between this costume and her SC one are in her hair, shoulderpads, and shoes.
Sophitia's hair is worn in a very low pony tail, and now she's got earings (fairly large silver hoops). The shoulderpads are slightly more flat than her Soul Calibur ones, and a chain connects the two broaches on her shoulder straps. The pattern on Sophitia's skirt is slightly different, and her sandals resemble her Soul Edge footwear more closely than her Soul Calibur footwear.
Sophitia's second costume in Soul Calibur II appears to me a better armored version of her secondary costume in Soul Calibur. She wears her hair down in this outfit, her bangs are much longer and parted to frame her face and she wears a thin silver headband.
She wears a pair of long red gloves, though the right arm is longer than the other and comes up to connect with the long pink sash that holds the whole outfit together. Her arms are protected by wrist guards and metal shoulder guards. She wears a silver breastplate which is held in place by leather straps and the pink sash that runs wraps around her neck and runs down her front. Her entire body is wrapped in a large cream skirt with a simple Greecian design at the bottom. The skirt is held tight by a leather belt with silver clasp. The 'skirt' only seems to wrap itself around one and a half times, as there's a fairly large slit up the left side providing better movement.
Sophitia's third and final costume in SCII can be recognized by anyone who managed to get all of her costumes in soul edge. It is simply a brown haired version of Sophitia in her 'underwear' or training clothes. A simple white dress with long brown boots and long brown gloves with finger holes cut out.
Sophitia actually has a number of other outfits, however as my access to screen-cap utilities is absolutely nil. Other outfits include a bathing suit, something that resembles a Scottish kilt, and 'nothing'--all from soul edge; and a more conservative, more pink 3rd outfit for Soul Calibur. Once images are available for these I'll put them up with an analysis! Please feel FREE to make contributions!!
