Katharine Hepburn always stuck to her guns when it came to fashion. At a time when androgynous dressing was unorthodox, she sported menswear-inspired blazers, collared shirts, trousers, and loafers — carving out a style all her own in the Hollywood spotlight. As an homage to the Oscar-winning actress' idiosyncratic approach to clothes, we're looking back at some of her most memorable looks, both on and off screen.
