Cruella Deville is a memorable Disney villain. A mad, fur-coat collector is not a good person when the heroes are Dalmatian puppies! (Or most times for that matter). Cruella’s wig is and French style long cigarette holder is probably the most iconic aspect of the costume.
Cruella always wears red gloves with a black dress and usually some sort of white fur coat. You can get the entire look here. For a faux-fur white coat try this.
Dalmatian optional.
