Hanne is 20 years old. She is short, 5'2", a little bit overweight, and very curvy. Exceedingly busty. Big hips, big boobs, a full sort of figure. Her eyes are a hazel-y green, seeming to become more green or more brown depending on what she's wearing. Her hair is a dark brown, curly in an unmanageably wild kind of way, not in a neat ringlet kind of way - because of this, she usually wears it pulled back in various styles of updos and buns and whatnot. Her face is young and has a cute look to it, with an upturned nose. Her skin is slightly tanned, just from working out in the sun so much.
Clothing is generally in shades of green and blue and black and brown and cream - earthy and natural sorts of colors. Some maroons and deep reds too. Not bright cheery colors, but down to earth colors. She likes to be revealing but practical; she wants to wear heels but knows she shouldn't, so she compromises by wearing heeled bootss - this is an example of what she'll do. She almost always wears pants, because skirts are too dangerous, but she'll wear tight pants to make up for it. She likes low cut blouses.
There is a mark on her left arm, from about halfway up her neck to her elbow. It's a tribal symbol that I haven't really developed yet, but that's okay because it should be hidden anyway. It's Trouble, it's part of what gives her her magic, and so she usually keeps it covered up - which means that on that side at least she usually wears things with a high collar and long sleeves.
Details you could choose to include are a ring on her right hand and a pearl pin that she usually wears somewhere on her person. Her weapon of choice would be guns, I'd say.
Since she's from a post-apocalyptic, Western-ish world, cowboy boots and a hat are pretty necessary!
