For the record: Stacy London, longtime co-host of TV’s “What Not to Wear,” is wearing a glittery Christmas-tree-green pencil skirt, a black crew neck sweater with a cat’s face on the front, chunky green jewelry and a pair of textured stilettos with thick ankle straps. (Jean-Michel Cazabat, she says, of the shoes.) It’s a bold and unusual mix, and she wears it happily, describing it as an outfit full of “joy and whimsy.”
