Mirage lives in a forest that is always frozen. It's always snowing. However if she does leave the forest and goes into warmer climates for a while she changes her coat like any arctic fox, her fur and hair becoming shorter~
A ref sheet of my fursona, Mirage! Her massive tail and long hair are probably her biggest traits~ Changes were done to her paws, now being covered in black fur instead of just the fingertips, as well as pawpads!!
