Proenza Schouler launched its first handbag collection in 2008 with the PS1, a classic satchel that embodies a sense of wearable luxury that has become the brand’s signature.

The inspiration for the PS1 bag was drawn from traditional work-wear satchels, but the material is reinterpreted in soft lux leather that gives the bag a relaxed ease. The name PS1 stands for the first Proenza Schouler bag, and is a riff on the way New York City public schools are named by the initials “P.S.” and a number.
