Dressing well and following a suitable style helps you stand out from the crowd. It affects your personality and shows you as a confident person.
People wear a blazer or a suit for formal occasions. But they sometimes intermingle these terms and consider them the same.
It is these small details that can make or break a look. Even some shop retailers do not know the difference between them. But some interviewers take special notice of these small changes.
When a person enters a room, he makes his first impression through his appearance and his dress. If the person has taken this lightly and wore a suit or a jacket instead of a blazer, it might deduct his marks or even cost him his job.
So, the corporate sector does not compromise on the dressing part. That is because; these employers are further going to represent their company or their product.
If their employers do not know the difference between a blazer and a suit and when to wear it, then this might affect the whole company’s reputation.

What is Blazer?
The term for blazer first originated around 1825. The members of the Lady Margaret Boat Clun and the Rowing Club used to wear blazers of red colour, and that is why they were called blazers initiated from “blaze”.
A blazer can be worn with pants of different fabrics and even different colours. A blazer creates its own identity. They commonly come in a navy blue colour. But these days, they are being manufactured in every colour.
As time evolves, so does the design of clothes. Blazers come in different patterns like monochrome and flowers and can have fancy pockets.
Tailors have sufficient knowledge regarding the stitching of the suit and a blazer. A blazer does not contain inner padding near the shoulders.
This makes the shape of the blazer rounded from the shoulders and hence, follows the natural shape of the shoulders. This thing is referred to as “camicia”.
A blazer is not stiff rather it is a comfortable piece of clothing. It can be over multiple layers of clothing. It has loose-fitting and is not stuck to the body. It can be worn anywhere where you do not need to look formal but still have to dress up nicely.

What is Suit?
The term first originated in England in the XIX century as jaquette. But then the design changed and resembled the modern type of suit today. It was square-shaped and reached to the thighs.
A suit jacket is worn with pants of the same fabric and sometimes even with a vest. They are strictly worn on formal occasions like business meetings or wedding occasions.
A suit jacket’s shoulders are called “rollino”, meaning they have a pad inserted into the shoulder area to make it well-defined. A sleeve is attached separately to the rest, and it forms that stiff structure.
A suit does not have patterns of any fancy designs because it needs to look decent in a business context and for wedding ceremonies. It also does not have a lot of packets.
The primary colours used for a suit are primarily navy blue, brown, and black. A suit is a slim-fit dress, so it should be worn with a shirt underneath and nothing else.
