A blazer is all about the shoulders. Get those right and the rest can often be tailored.

Measure

  • Chest: around the fullest part, under the arms.
  • Shoulders: from one shoulder point to the other across the back.
  • Sleeve: from the shoulder seam to the wrist bone.

Compare to the chart

Every brand cuts differently. Compare your numbers with the brand's size chart, not your usual size letter.

Fit notes

Slim, regular and relaxed fits describe the cut. Check the listing and the retailer's return terms before ordering.
