When Princess Mary joined the rest of the Danish royal family for a photo call at Grasten Castle in Denmark, she looked far more casual than regal. No crowns, brooches, or flashy jewels in sight, Mary slipped into a bohemian-style midi from Sea New York [1], which featured a paisley print and two cream tassels. It's the type of design we like to keep on hand for our own group gatherings, whether for a beach vacation or a sunset dinner.

Mary added modest touches to her look, like pearl drop earrings [2] and a black cardigan, and she secured the strings of her dress at the neckline. Finishing her outfit with cognac sandals and a few bracelets, Mary looked sophisticated [3], but completely carefree as she celebrated the Summer in good company.
