How to Measure

  • Width: Measured flat across the chest from armhole seam to armhole seam.
  • Length: From the highest point of the shoulder (neck seam) straight down to the hem.
  • Sleeve length from center back: From the center back neck, across the shoulder, to the end of the sleeve.
  • Compare these measurements with a polo or shirt you already own and love the fit of.
This polo runs large. If you are between sizes, we recommend sizing down for a more fitted look, or staying true to size for a relaxed, casual fit.
