What's the Difference? Sport Coats, Blazers, and Suit Jackets

How are sport coats, blazers, and suit jackets different in men’s clothing? Unsurprisingly, the rules are also different for how men wear these garments compared to how women wear them.

Sport Coat

Sport coat…sports coat…sport jacket…all these terms can be used interchangeably. A sport coat was traditionally worn during the day or while doing outdoor “sporting” activities like hunting.

For this purpose, the fit was looser since it was intended to be layered and to allow movement. The fabric was also more rugged, with a rougher texture. A sport coat can be made in an array of pattern and color: tweeds, houndstooth, herringbone, etc. Details like elbow patches, pleats, pockets, and belts also reference the original function of sport jackets.

Blazer

A blazer is in-between in terms of formality, as is the structured fit. Traditionally, blazers were navy wool with (gold) buttons. A blazer is a great choice for any time a suit is too dressed up. While the fabric is dressy, the colors and the non-matching bottoms make an outfit less formal.

Fun Fact: the term “blazer” originates from the bright red color of the flannel jackets worn by the Lady Margaret Boating Club at Cambridge.

Suit Jacket

A suit jacket always has matching pieces: trousers and a vest for men, or a skirt, dress, and pants for women. While I often recommend that women split up a suit to get the most wear from the different pieces (but dry-clean them together!), that advice does not apply to men.

A suit is the most formal style of clothing of the ones described here. For men, that means the pieces should always be worn together. A suit will be the most tailored, with the jacket fitting more snugly than a sport coat or blazer. The weave is typically more subtle, the fabric typically a fine wool with a slight sheen, and the colors and patterns usually somber.

I wanted to tell you how much I've enjoyed wearing the two suits you made me! I've owned many suits through the years but these are without an equal. The fit, the workmanship, the attention to detail all excellent! They really do "fit like a glove". I must be honest and tell you that I was prepared to have to try them on and wait for them to be adjusted one last time before I could take them home, but no they fit perfect, just like you said they would. I haven't even mentioned the shirts, they are as high quality as well. "I love them". Last but not least, doing business with you was a pleasure. Everything arrived on time (2 days ahead of schedule) as you promised. I will recommend you to all my associates. You are a man of our word, doing business on a trusted hand shake is a time honored quality that never goes out of style. Take care and I'll be in touch when I'm ready for my next clothing purchase.
