Nicole Kidman showed some PDA on the beach in Sydney, Australia with husband Keith Urban, but her swimwear? It was as sophisticated as ever. The Big Little Lies star sported a frilly polka-dot bikini with a wide brim hat and large mirrored sunglasses. Her bandeau top didn't just feature a peplum skirt, but a ruffle across the neckline, making it a flirty little ensemble. Nicole's appearance was a reminder to us all that polka dots are just as classic as a triangle two-piece. Scroll for a second glance, then shop some similar designs we found.
