Designer Sophie Theallet—known and prized for her feminine silhouettes rendered in elegant fabrics—turned to an unusual source for inspiration for a new limited-edition line: the interiors of The Gramercy Park Hotel. The collection is part of a collaboration with the hotel, and will be featured in its Rose Bar and Gramercy Terrace. Aby and Samantha Boardman fêted Theallet and the new collaboration at its new home, with friends including Rula Jebreal, Alina Cho, Hannah Bronfman, Fernanda Niven, and many others.
