Some of these I know pretty well, but not so much the others.
Nephthys sticks to desert tones - browns, reds, creams - and often is in long skirts and long dresses.
Eisheth likes to do classy-sexy and with lots of forties sort of touches, well-tailored dresses, and high-waisted pencil skirts. She enjoys being a 'lady'.
Fashion will be found in whatever happens to be in style at that very moment. Obviously ;)
Metal is usually a black jeans and band t-shirt kind of a girl, and when she dresses up it's in black with lots of leather and metal.
Both Tlazolteotl and The Keres dress in whatever they find lying around, as they're both homeless and don't give a damn about fashion. They both also steal clothes from the dead, so Tlaz is often wearing rather slutty things as she preys on prostitutes.
Hathor likes to wear things that are clinging, sexy and revealing. Basically she'll wear anything that shows off her curves.
Ate doesn't really have a 'style' herself, but she does like mini-dresses and her adoration of shoes means she'll buy clothes based on whatever will go with them.
