The Difference Between a Blazer, Sports Jacket, and a Suit Jacket
What is the difference between the three jackets in a men's wardrobe?
This is very simple:
BLAZER
A blazer is a double-breasted jacket either in blue (below) or black with gold buttons. They have evolved over the years and could be single breasted as well like the one to the left. Personally, this reminds me of an era gone by and/or an airline uniform.
It looks stylish, but where?
SPORTS JACKET
A sports jacket is what people mistaken for a blazer. A sports jacket is a jacket made from a thicker fabric you wouldn't necessarily use for pants. It typically has a bigger pattern and not constructed "tight" as a suit jacket. What's a suit jacket you ask? Good question.

Sport jackets can be fun (left) or serious (right) but note the fabric. The one on the right wouldn't look right with a matching trouser.
SUIT JACKET
A suit jacket is exactly what it sounds like. It's a jacket that matches the trousers and the two become a suit, hence suit jacket and suit trouser. A suit jacket will be made from a finer fabric and can come in many different patterns (like a pinstripe, plain, plaid, etc). Below is Tony modeling his Zaharoff suit, which comprises of a suit jacket and a trouser.
DO NOT weat a suit jacket with out it's suit pants - when you do, it's called an "orphaned jacket" - so no orphans!

I usually used a suit jacket, cause it fits my lifestyle..Good thing for pointing out distinction.
Hello
thanks to your explanation about Blazers. I have a Blazer jake, which is exactly like the first picture you submitted(top-left dark blue blazer with six botton and wide collar). But i heard from some friends that it is too old fashion specially because of its wide collar. although I know that blazers normally have classic style and do not evolve too much during the time, but please let me know is this blazer too old fashion?
this the page you submitted the photo of blazers

Hi Fashad, thanks for your note - in regards to your question...the db is somewhat making a comeback. The jacket in the picture - if it exactly like that, lapels and all, it's perfect.
