What is the difference between blazers, sports coats, and suit jackets?

What is a Blazer?

Blazers are one level higher than sports coats but lower than suit jackets. It can function as an all-rounder. Unlike the suit jacket below, a blazer does not come with a matching pair of pants. In the old days, a blazer was made of wool, had a blue color, a pocket, and silver or gold buttons. Today, however, this is no longer true and blazers often come in cotton, other colors and different types of buttons. Blazers are often worn in the so-called business casual look, meaning combined with jeans and a shirt.

Difference between Sportcoat and Suit?

Sportcoats are, as the name already indicates, the least formal of all three jacket types. The sports coat originates from hunting or other sport related activities in the old days. Therefore it was made of more robust fabric such as tweet (e.g. hounds tooth or donegal) and was often patterned with more colorful designs than the two more formal variants.

What is a Suit Jacket?

The classic suit jacket which is often combined with suit pants made out of the same fabric. It is mostly made from fine wool. Different fabric weights can cater for warmer or colder climates. For summer, cotton or linen suits are also available. It is quite important that the suit jacket and the pants match up. Hence it is not recommended to wear the suit jacket for example with jeans or khaki as this can result in the jacket having a difference of color vs. the pants.

How to measure your suit jacket size?

  • Chest: The chest is the most important body part if it comes to finding the right size for your sports coat, suit jacket or blazer. Measure around fullest part of your chest. Hold the measuring tape just under your arms and then extend around your shoulder blades. Please, hold the measuring tape level and parallel to ground.
  • Waist: Measure just below your waist at the height where you normally wear your pants (approx. 1 inch below your belly button). Ideally, keep one finger between the measuring tape and your body.
  • Sleeve: Measure from the center back of your neck, over your shoulder, down on the outside of your arm to your wrist. It’s best if you bend your arm slightly while measuring.
  • Neck: Either wrap the measuring tape around your throat while keeping a finger between the measuring tape and your neck or better: take a shirt that fits you well in the collar and measure from the center of the collar button to the end of buttonhole.
