The chic and cheeky Ashley Longshore has taken the fashion world by storm. After conquering Fifth Avenue (and creating the most Insta-worthy cafe in NYC), the artist has set her colorful sights on - where else? - The Hamptons.

This weekend, Lizzie Tisch teamed up with Longshore for a two-day bash launching LTD, Tisch's new experiential style venture which will see limited edition collabs with artists and designers.

The expansive gardens of a private estate in Water Mill were turned into an Alice In Wonderland-esque maze of hedges and paintings, dotted with whimsical touches all around. (Pretty much what we'd imagine living in a Longshore piece is like.) On Friday, the likes of Sarah Jessica Parker, Kelly Ripa, and Jane Krakowski stopped by for an exclusive dinner and VIP preview of the installation, which, on Saturday, featured a curated selection of shoppable must-haves from Blushington, Lingua Franca, and more. No wonder such a well-heeled crowd came out to celebrate!
