Olivia Wilde’s Michael Kors print dress is the perfect day-to-night look, while Olivia Palermo keeps it casual with a boyfriend-fit shirt-dress.

A staple for tastemakers like Olivia Wilde, Jessica Alba, Olivia Palermo and Jennifer Lawrence, the shirt-dress works for any style type and is warm-weather friendly, making it summer’s easiest must-have. This menswear-inspired shift is best worn loosely (paired with sandals or flats) for a simple, dressed-down look. Take your shirt-dress from day to night by adding a statement heel and a waist-cinching belt.
