Reese Witherspoon isn’t just the majority shareholder in Draper James, but its biggest fan. At any given time, her Instagram page is peppered with the brand’s wares, from her custom birthday dress to her summer-ready gingham faves. Now, the Big Little Lies star, 41, has expanded her fashion empire even further with a collaboration with Net-a-Porter and invited her “nearest and dearest” to help her celebrate (and model) the launch.

Witherspoon’s lookalike daughter Ava Phillippe (dad is ex Ryan Phillippe) wowed in a pink-and-blue Dolly Cold-Shoulder Dress ($450), while her mom sparkled in her own embellished Silk and Cotton Blend Dress ($550).

Beyond her family, Witherspoon also tapped some of her famous friends to show Instagram just how summer-perfect (and gingham-fabulous) the collection is.

Celeb pals including Camila Alves, Chelsea Handler, Jennifer Garner, Molly Sims, Rachel Zoe, and Louise Roe looked glorious in the various designs featuring preppy A-line cuts, lace eyelet detailing, and gingham prints galore.
