Lady Edith Crawley (Laura Carmichael), Downton Abbey
As a liberated young woman of the 1920s, the second Crawley sister is dressing the part after years of dowdy duds. Diaphanous gowns in vibrant tones like coral or Tiffany blue are show-stoppers, especially when they scandalously leave her shoulders bare. Elaborate beading and a bohemian sensibility also reflect Lady Edith's newfound sense of feminine rebelliousness. After living in the shadow of her older sister, Edith is making her presence known in a big and fashionable way.
