Former DJ and luxury watch company Gomelsky’s creative director Cassie Coane married at the 86-acre Southwood Estate in Upstate New York this past weekend. The bohemian bride was ethereal in a dress from Danielle Frankel Studio with lightweight layers, a gauzy overlay, sheer sleeves, and a lace train. Friends Harley Viera Newton, Mary-Kate Olsen, and Ashley Olsen all played supporting roles as bridesmaids (there were 18 total), wearing colorful floral frocks they’d chosen themselves in vibrant summer colors. Unsurprisingly, the Olsens went vintage—with Mary-Kate in a yellow flower-printed cocktail dress with kimono sleeves and bright green pointy-toed mules. Meanwhile, Ashley opted for a black cocktail dress also with a billowing sleeve, white floral embellishments, and statement earrings. The whole bridal moment looks like it’s straight out of Sofia Coppola’s The Virgin Suicides or fashion’s favorite documentary, The Source Family—and we couldn’t love it any more!
