Queen Elizabeth, fashion icon? Yes.

She undoubtedly had a uniform that helped set a standard for womenswear in politics and diplomacy.

For decades now, it has been relatively easy to dress up — for Halloween, maybe, or for laughs at any given royal-wedding or Jubilee watch party — as the Queen of England. All one needs, so the common wisdom goes, are a solid and brightly colored boxy skirt suit with a brooch on the left shoulder, a matching hat (or, for extra credit, umbrella) and white gloves, with a handbag swinging gently on one forearm. And perhaps a white wig.
