First lady Dr. Jill Biden stepped off a plane last week in a short black leather skirt, black patterned tights (floral fishnets, InStyle called them) and black stiletto booties. Cue the uproar. Some on Twitter deemed her ensemble — often in quite unkind terms — more appropriate for a woman half her age and nowhere near her station. Others sprang to her defense, called the look “rockin'” and “classy,” and noted the inherent sexism of the criticism.
