Hilary Duff and her big sister Haylie Duff attended their friend Erin Wolford’s wedding over the weekend, and the gorgeous girls turned the nuptials into a fun sister trip. Hilary took to Instagram on Monday to share a sweet bikini-clad selfie from their beach weekend and, unsurprisingly, the stunning sisters look seriously similar to each other.

In the photo, the Lizzie McGuire alum appears fresh-faced, has her blonde strands pulled up into a bun, and shows off her curves in a floral string bikini. Haylie is gorgeous in a white scalloped bikini with high-waist bottoms and wears her short blonde hair down. The talented sisters have never looked more alike as they show off their dazzling eyes and matching bright whites. "My seester..." Hilary wrote in the post's caption.

The 31-year-old big sister shared a similar photo, in which the girls show off their wide smiles with a friend on the beach. “#ErinAndDannyWeddingWeekend #danceswithwolfs,” she captioned the photo on Friday.

Of course, it comes as no surprise that these two were stunning wedding guests. The 28-year-old Younger star showed off a gorgeous black-and-white photograph, where the sisters stun in long floral maxis on the big day. “@erinlhaggerty you were the most beautiful bride! We love you,” she wrote.
