Wendy Jill Freedman, founder of the beloved West Hollywood vintage boutique Polkadots and Moonbeams with clients like Julia Roberts, Drew Barrymore and Lily Collins, has died. She was 66.

Freedman died Friday in Santa Monica after a long battle with breast cancer.

For more than four decades, Freedman built Polkadots and Moonbeams into a fashion institution for customers and costume designers alike, supplying pieces from productions including Emily in Paris, Modern Family, This Is Us and The Marvelous Mrs. Maisel.

Born on June 26, 1959, in Chicago, Freedman’s sense of fashion was heavily influenced by her mother and grandmother, who were lovers of couture and vintage finds.

“The dichotomy between my couture mother and my treasure hunting grandmother, helped me realize the disparity in the market for wearable vintage fashion in West Hollywood,” Freedman said in a past interview.
