The actress – who plays Scarlet Witch in Avengers: Age Of Ultron – arrived at JFK airport wearing a simple black tunic with matching trousers and brown leather sandals on her feet.

Elizabeth covered her eyes with a pair of black sunglasses and carried a wide-brimmed straw hat in her hands.

She’s known for her modest style, and Olsen’s travelling ensemble seemed the perfect choice for a flight.

But on Tuesday she showed off her sculpted legs in a buttoned charcoal mini skirt as she made a promotional appearance at the Apple store in New York’s Soho neighbourhood.

The 26-year-old actress still appeared sophisticated, teaming her conservative skirt with a loose black turtleneck jacket.
