Which handbag brand is known for the PS1, a satchel designed by Proenza Schouler?

Proenza Schouler is known for the PS1, a satchel that became one of the label’s signature accessories.

The PS1 was designed by Jack McCollough and Lazaro Hernandez, the founders of Proenza Schouler. It has a schoolbag-inspired shape, a flap secured by straps, a top handle, and a detachable shoulder strap. The design was part of the brand’s move from runway fashion into highly recognizable accessories.

The name PS1 refers to the initials of Proenza Schouler and the number one. It is sometimes confused with later Proenza Schouler bags, including the PS11, but the PS1 is the more traditional satchel with a softer, bookish profile. Proenza Schouler was founded in New York in 2002.
