Leave it to Charlize Theron to grab an over-sized sleep shirt from her beau's closet and rock it like red carpet royalty. Sure, this might not actually be Sean Penn's clothing, but this thing looks like a t-shirt and it looks perfect on the A Million Ways to Die in the West star. Not that the South African stunner needs any help from her fashion... Her fit frame, long legs and classic pop of color on the lips could sell a burlap bag, which is essentially what she's wearing, in black. The Prometheus star also opted against blingy accessories or detailed shoes.
