Margot Robbie puts on a leggy display in a polka dot mini dress (but sports a plaster on her knee)

She’s set to play a real-life Barbie in a new film directed by Greta Gerwig.

The Australian beauty looked incredible in a polka dot minidress by Polish designer Magda Butrym, but things weren’t all fun and games as Robbie was seen with a Band-Aid on her knee.
