Margot Robbie Just Wore a Polarizing Swimsuit Trend in France

If you thought Margot Robbie's Cannes red carpet looks were stellar, take a peek at her equally chic off-duty swimwear style. After turning heads in a Chanel dress-over-pants outfit at the premiere of her new film, Once Upon a Time in Hollywood, Robbie took a dip in the ocean at the famed Hotel du Cap-Eden-Roc, a luxury resort in the middle of all the action during the Cannes Film Festival.
She wore a sleek, elegant one-shoulder white swimsuit, which is pretty much a minimalist's dream summer look. However, white swimsuits can be a polarizing trend because of their tendency to become see-through after swimming, making them a bit tricky to pull off. Whether you love white swimsuits or prefer less risky dark-colored options, there's no doubting that Robbie has French Riveria summer style down pat. Scroll down to see how she wore a one-shoulder white swimsuit, and shop similar pieces for yourself—no flight to France required.

After nearly three years at R29, she came back to WWW in 2015, where she is now the Associate Director of Fashion News.
