Mary-Kate and Ashley Olsen Look Carefree During Their Bikini-Clad Vacation in France

Mary-Kate and Ashley Olsen looked calm and relaxed during their recent vacation in Antibes, France, over the weekend. Wearing similar black bathing suits, the fashion designers flashed sweet smiles as they took a dip in the water at the Hotel du Cap-Eden-Roc. While Ashley mingled with a few friends during the outing, Mary-Kate was joined by her husband, Olivier Sarkozy.

This is just the latest we've seen of the 30-year-olds. Not only did they join their little sister, Elizabeth, for the opening of their LA flagship store back in July, but Mary-Kate has recently been showing off her equestrian skills at various horse shows in New York.
