Italian sizing varies between brands, so letter sizes are indicative. The item's own measurements are the safest guide.

  • Shoulder: lay a jacket or shirt that fits you well flat and measure seam to seam across the back.
  • Chest: underarm to underarm with the garment flat. Double it to get the circumference.
  • Sleeve: from the shoulder seam to the end of the cuff.
  • Length: from the bottom of the collar to the hem, on the back.

  • Construction: Full Canvas (Fully Lined). Built with a traditional floating full canvas horsehair interlining that molds to the wearer's chest over time, paired with a complete 100% cupro lining for optimal shape retention, durability, and a smooth drape.
