OK, we are all kind of amazed and grossed out when Allison draws a beautiful snow-covered bridge picture, then makes it "snow" by shaking her dandruff onto the paper. Throughout the movie, she is wearing a black sweater, and not a single flake is to be seen on her clothes.
Also, up until her little make over, she is an early Goth with over-dyed black hair...When Claire gave her the make over, did she just happen to have a bottle of Miss Clairol's soft brown hair-dye in her bag, too?
