See, now this is just asking for tl;dr. ._. I love clothing so much.
Martel: Chimaera is practical to the core. She doesn't understand the concept of clothing as an aesthetic, so her outfits of choice are all very functional. She likes cargoes and pants with lots of pockets to carry things because she doesn't like bags, and she usually wears either tank tops or t-shirts. Colour doesn't matter. In addition to this, she wears just about whatever Greed tells her to wear, though if it's a dress she'll whine about it because she thinks skirts are difficult to move in.
Kumiho: Clothing is extremely important for Kumiho; it's how she defines herself. You can usually tell a lot about whatever personality she's currently acting by her clothing, as she often functions around stereotypes. I don't lie when I say she has almost everything in her closet, though she's ashamed of having certain articles so she keeps them hidden. Her main persona dresses very chique. She's elegant, classy, and doesn't usually have much tolerance for the eccentricities of some designer clothing. She hates hipster clothing but she has a whole drawer full of it, including [shamefully enough] a pair of shutter frames hidden in a box where she likes to pretend they don't exist most of the time. There are some infrequently worn t-shirts, jeans, and other such casual things, that are only pulled out once in a blue moon when she's in the right state of mind. She has precious few oriental-themed items, because while she likes them and all, she despises the fact that people seem to expect Asians to fixate around the styles of their culture. Christ, stop being stereotypical, America. >:| Still, despite her fondness of clothing, Kumiho likes being naked more than she probably should.
Eve: It feels wrong to have her go after Kumiho. Eve has nice clothing... for Sundays. She feels uncomfortable in dresses--though long skirts are okay sometimes, for whatever reason--so they're usually just blouses and nice pants. Most of the time Eve wears blue jeans sporting various levels of wear and tear, and plain, unimaginative shirts. She spends the majority of her days engaging in physical labour, so she really doesn't see the point of dressing fancy to just get covered in dirt or oil or dust or whatever. Currently, she only owns one dress, which is an unspectacular all-white sundress with a long skirt and no sleeves. Three hundred and sixty-two days of the year it is gathering dust in the back of her closet.
Boudicca: Probably the only one of my current brood who comfortably wears both casual and formal clothing on a regular basis. Boudicca is pretty standard--skirts or pants, blouses, knee-length dresses to work, long affairs and formal things to parties, and typically whatever she feels like wearing when she has nothing better to do. She dresses impeccably, no matter what she's wearing, with a good amount of tasteful accessories because she has a fondness for shiny things. When working out she tends to opt toward As Little As Possible without looking like a slutty teenybopper, but she wouldn't touch spandex if you paid her.
Sloth: Lmfao. :| Sloth wears typical shrug clothing. Hoodies, jeans, cargoes, pajama pants, sweat pants, t-shirts, et cetera. She doesn't care how she looks or what she wears, and often her clothes are rumpled because she tends to fall asleep while wearing them. When it comes to formal wear Sloth will always prefer a suit over a dress.
