Updated Feb. 17: The closure is now official.
According to an outgoing message on the shop's phone, this is a temporary closure for "building maintenance." (One local said it was related to a mold issue.) Rumors were circulating late last week that this shop has closed for good. This location is not listed on the Eileen Fisher website, and Google notes it as permanently closed.
This was Fisher's first location, opening in 1987 (per this New Yorker feature on her from 2013). Her brand grew to 50-plus shops around the country and sales in various department stores.
Manhattan Sideways wrote this about the Ninth Street outpost: "[I]t is not even owned by the larger corporation behind the other shops, but rather by Eileen Fisher herself. Sample garments are sold here – some that never made it into production. Many of the pieces found here are different from what is in the rest of the line each season."
