Okay, I think I've got something for you:
I kept the face, hair, and bow. I went with a short-sleeved jacket as a sort-of remnant from the "sweet girl" days (since it looks a bit like a t-shirt) and put a bit of blue in there to match her hair and make the costume more interesting. I used the Arctic pattern on the gloves, pants, and boots because of her ice powers. I tried to mostly use blacks, greys, and dark colors, but since her hair stands out, I felt okay making her chest detail stand out a bit. Anyway, I hope you like it!
The costume file is attached.
