Last night at the Julie & Julia screening in Hollywood, Yvonne Strahovski, who plays awesome CIA agent Sarah on NBC's sitcom Chuck, walked down the red carpet seemingly without professional assistance. Her hair was unstyled, no glamorous premiere makeup was to be found, and she was wearing a t-shirt and jeans. Yvonne's naturally beautiful — she'd look good in a potato sack, as my mother would say — but she was more casual than other guests. Do you find this low-key approach refreshing, or do you prefer a more done-up look?
