It may look ho-hum Tudor, but you must imagine it in color: pink and silver brocade over vivid cranberry-colored underskirt, the cranberry bands on the sleeves all individually hemmed in small, perfect rows of seed pearls. White ruff and lace fan collar. Jewels, of course, though they hardly matter beside the color.
Bette Davis inhabits a gown by the legendary Orry-Kelly, in The Private Lives of Elizabeth and Essex. Oh yes, there's Errol Flynn too, but somehow one forgets him.
