Open Side Blazer | Black

  • Description
  • Size & Fit
  • Fabric & Care

Designer's Note: The starting point is a classic suit jacket, but the construction is deliberately lighter. The sides are left open so the layer underneath becomes part of the silhouette, and it can transform with you. Two straps sit at the waist and can be worn loose or pulled through the loops and closed like a belt. Inside, the jacket is built with light horsehair and light interfacing, half lined in pongee, with bound seams, an inside pocket and two side-seam pockets. Functional sleeve vents with working buttons and a traditionally constructed collar keep the tailoring intact. The result is a light, precisely constructed jacket that can be worn open, belted or somewhere in between.
