What is the difference between a suit, blazer and a jacket?

Answer 1

I'll answer your question in male terms. It will make the answer shorter.

A suit is a two piece outfit consisting of a jacket and pants of the same fabric.

A blazer is a type of "sport jacket." If you want the real story, back in the late 1800's and early 1900's there was a US Navy ship called the US Blazer. The captain wanted a more unique uniform for his officers. And this consisted of a navy blue sports jacket with gold buttons, to be worn with dark gray pants.

This style jacket was incorporated into mainstay fashion and was called "The Blazer." So in strict fashion terms the Blazer is the dressiest sports jacket and it's a solid navy blue with gold buttons. And in many instances, the blazer worn with charcoal gary (dark gray) pants is considered as dressy as a suit.

Nowadays, the blazer has taken on a more loose definition, as it encompasses any kind of solid coloured sports coat, as long as it's tailored like a suit jacket.

A jacket is any other kind of "sports coat" that is not a blazer. Of these there are myriad styles and looks available.

Answer 2

A suit is a set of clothing. Usually some high dollar name brand that stock traders and very important people wear.

A blazer is the top half of a suit. What you see some guys wearing with jeans.

A jacket is a jacket. Like you wear when you are cold.

Answer 3

a suit is the pants and the jacket, a blazer is just the jacket, and a acket is a jacket. To shield you from the elements.
