Miley Cyrus has an edgy, boho chic sense of style -- and that's exactly how she worked this feminine polka dot frock! She added a little edge to her mini, pairing it with boots. Her casual polka dot frock had a cool retro feel -- and you can easily dress it up or down! If you want to get the look, SHOP my picks and add your own personal flair to the ensemble -- just like Miley did!
