Rose Byrne attended DKNY’s #DKKNYARTWORKS Charity Auction in Montauk, New York to raise money for Free Arts NYC, an organization that provides under-served children and families with educational arts and mentoring programs wearing a summery eyelet dress by the brand. The 100% cotton design is ideal for hot summer nights, and while the sleeveless drop-waist dress is sold out in white, you can still snag it in black. Shop the style for $315 at
