The former child actors, who have built a global fashion empire in their short 28 years, created the gorgeous ivory white gown for their childhood friend, stylist Molly Fishkin for her wedding to producer/director Asher Levin in Los Angeles on June 7, 2014.

“The minute I got engaged, they said they would love to design my wedding dress,” the bride told Vogue magazine, who shot the wedding.

“I was thrilled—their taste is impeccable, and I really trust them. Their team was so incredible and patient with me. They were always so calming and made the process incredibly enjoyable. I will never forget what they did for me.”
