Oxford shirts are made to be paired with suits, but we admire how Zoe Saldana turned hers on its head at a recent movie event in Hollywood. The actress tucked her light blue oxford into a pair of ripped skinny jeans, making the contrast between preppy and edgy super fresh. She then finished off her crisp-cool look with tan ankle booties and black-rimmed glasses. If you don't already own an oxford shirt, invest in one with contrast piping, like Zoe's, or a solid one sans piping works, too. Tuck it into skinny jeans now — a red pair would be fun, too — then come Summer, throw it on over a pair of denim cutoffs for extra sass. Then when you have a serious work meeting, tuck it into a slim pencil skirt to appear chic to the max.
