Were approaching the final days of summer, and New Yorks fashion crowd spent Thursday evening celebrating the belovedDoenfounders, Margaret and Katherine Kleveland, and their newest endeavor: aSag Harborstore.

For those unfamiliar with the backstory of the cult favorite brand Doen, it began in 2016, when the two sisters created a quintessential California wardrobe full of vintage-inspired bohemian dresses.

Then, they met two editors, Laura Brown and Kristina ONeill, who fell in love with the brands romantic floral prints and helped throw the weight of the New York fashion scene behind them.

Yesterday evening, the pair teamed up again to help welcome the West Coast sisters to the Hamptons with an outdoor soiree at The Maidstone in Easthampton.

The evening began at sunset with cocktails at the garden of The Maidstone alongside plenty of loyal Doen fans, including Naomi Watts, Emily Weiss, and Rachel Zoe.

It was a breezy summer night: perfect for wearing a look from the Doen sisters pre-fall collectionincluding striped sweaters and moodier floral printsthat recently launched in stores.

During the dinner in Easthampton, the two sisters kept things casual and intimate, with dinner served family-style and glasses ofAvalinewinemade by the sisters friends Katherine Power and Cameron Diazbeing poured.

Before the main course was served, Margaret, alongside Brown and ONeill, stood up to give a toast to celebrate the loyal community of Doen.

Seven years ago, we were a lesser-known West Coast brand, and there were two women that were these wildly accomplished New Yorkers that somehow decided to unconditionally believe in the brand, support us, give us contacts, and wear us all around the world, explained Kleveland of Brown and ONeill.

Tonight, to share with their community in New York a new store in Sag Harbor after having such an amazing response to having a physical presence in the West Village is a wonderful feeling.
