Lets see, it depends on the situation!
Alright bear with me, I snagged a few pictures from randomly around dA, since I dont have any other of her up right now, so keep in mind none of these have any association with me whatsoever XD
normal day wear would be something like the red dress, this
[link] (with those sleeves or sleeveless)/ or something similar from the top half, and regular pants/jeans
out fighting/training would be something like the one on the far left in this picture, though never very frilly
[link]colors normally reds (from deep red to soft muted reds)/ blacks/whites and purples/maroons
hope that helps! just ask if you need me to clear anything up!
and thats great its helping you ^^ especially drawing Venus and Siano together always gives me a nice little test, with the really strong height and body type differences >< good practice, lol XD
