The 2015 Screen Actors Guild (or SAG) Awards drew stylish stars from far and wide, and the red carpet at LA's Shrine Auditorium was awash with glittering dresses and glamorous gowns.

The Theory of Everything star Felicity Jones wowed in a pale-pink, off-the-shoulder beauty by Balenciaga and Clare Danes donned an olive-green Marc Jacobs frock.

Another star who rocked more than a hint of cleavage was newly engaged Sofia Vergara, who was red-hot in a figure-hugging scarlet gown. She accessorized with her handsome fiancé, Joe Manganiello on her arm.
