Major Differences Between Blazer and Suit Jacket

What Exactly Is a Blazer? 

The blazers appeared in 1825. The rowing club members in Cambridge were the first to wear these blazers. The blazers were basically jackets, but since they were red in color, they were called ‘Blazer.’

As the word ‘blaze’ depicted the bright red color of fabric, these jackets were named blazers. Afterward, every jacket, despite the color, was called a blazer. 

The blazers have created their own identity. While creating the blazers, the tailors kept in mind that blazers could be worn with mismatched trousers.

Hence, blazers do not necessarily need any matching pants or trousers to ace the look. Thus, it is no surprise that the blazers have a casual approach. 

What Exactly Is a Suit Jacket?

The word ‘Jaquette’ was first used in the late 14th century. The jaquette was longer than the jackets worn nowadays. They could reach the knees and included embroidery, paddings, or fur.

The resemblance to these jaquettes was first established through sports coats. These sports coats were designed to reach the hips and fit straight along with wide shoulders. They also included two pockets and a set of buttons. 

A suit jacket is part of formal attire, consisting of trousers, a vest, and a jacket. In recent times, men can be seen matching these suit jackets with chinos, jeans, and trousers of different colors. Typically, the suit jackets are meant to be worn above matching-colored trousers.

The Contrast Between Blazer And Suit Jacket


  • Blazer- The blazers gained worldwide recognition once the British Navy approved them in 1837. In the beginning, they were double-breasted along with six buttons. The original color was navy. Only the rowers used to wear the single-breasted blazers. The two buttons presented in these blazers allowed the rowers to move freely. 
  • Suit jacket- The origin of suit jackets traces back to the 17th century. These jackets, which were produced by king Charles II were the simplified dress form of the British kingdom.

    These suit jackets are preferred to be tight fitting as you don’t need to wear any dress shirt or sweater vest beneath it. 


  • Blazer- These blazers are meant to serve the casual purpose of dressing up. 
  • Suit jacket- For dressing up in a more formal way, suit jackets are preferred. 


  • Blazer- The blazers are tailored along with shirt-shoulders, which is also called a camicia. The technique of tailoring a shirt is the same as well. After tailoring the blazer, the remaining or extra cloth is stitched underneath the shoulder. Because of showing the natural shape of your shoulders, these blazers have a softer look. 
  • Suit jacket- Italian suit jackets are handmade; hence they take time to get ready as they consist of details. Firstly, thin padding is inserted then another padding is added below it. So, the sleeve is basically attached to the jacket’s body. This is also called Rollino. While the remaining structure and shape of the suit jacket remain well defined, the shoulders are made to appear round. 


  • Blazers- Since the blazers are used in a less formal way, they are usually designed in an unlined and unpadded way. They do not have the lapels on the edges themselves. The lightness of these blazers allows one to dress them over multiple shirts.
  • Suit jackets- These suit jackets maintain their softness and lightness by the method of interfacing. In this method, the hair canvas is extended to the bust from the shoulders.

    This will keep the smooth lines of the jacket undisturbed. The high quality of any suit jacket is decided upon by the basis of interior lining and lapels’ tailoring. 


The tailoring of the shoulders of blazers differs in these techniques:

  • Rollino
  • Camicia
  •  Neapolitan
  • Italian
  • English

Suit jackets- The fabrics used for making a suit jacket are of different types. These materials are often fine and light to wear. Some of them are listed below:
