She may have only been showing at London Fashion Week since 2008, but Mary Katrantzou is already enjoying the kind of success most fashion designers can only dream of. The Greek-born, London-trained talent is known for her bold, unique prints, incorporating items you'd never expect to see on clothing — think typewriters, keyboards, and fish tanks. Structured shapes and the famous lantern skirt have become her trademark, but over recent seasons her look has softened, with less emphasis on bold, bright color. We've enjoyed a more subdued palette of black, indigo, deep purple, and lavender, and silhouettes have softened, too, with more use of chiffon, silk, and satin. Celebrities know to look to Mary for memorable red carpet dresses that require very few accessories.
