Frequently Asked Questions

Can you wear a sport coat with jeans?

Absolutely — sport coats were designed for casual wear. Dark jeans with a textured sport coat is one of the best smart-casual combinations. Just make sure the sport coat fabric (tweed, flannel, linen) contrasts with the denim.

Is a blazer more formal than a sport coat?

Yes. Blazers sit between a suit jacket and a sport coat in formality. Their solid color and structured construction make them appropriate for business casual and smart-casual settings, while sport coats are best for casual occasions.

Can you wear a blazer as a suit jacket?

No. A suit jacket is designed to be worn with matching trousers in the same fabric. A blazer is meant to be worn with contrasting trousers. Wearing a blazer with non-matching pants that are close-but-not-exact in color looks like a mistake.

What color blazer should I buy first?

Navy. It's the most versatile blazer color and works with virtually every trouser color — gray, khaki, charcoal, white, and even dark jeans. A navy blazer is the single most useful jacket a man can own.

Can a sport coat be worn to a wedding?

It depends on the wedding's dress code. A sport coat works for casual outdoor weddings or rustic venues, but for formal or semi-formal weddings, a blazer or suit is more appropriate.

What's the difference between a blazer and a suit jacket?

A suit jacket is sold with matching trousers in identical fabric and should only be worn together. A blazer is a standalone jacket designed to pair with contrasting trousers. Suit jackets typically have more structured construction and are made from finer fabrics.

Are sport coats out of style?

Not at all. Sport coats are a timeless menswear staple. Textured sport coats in tweed, flannel, and herringbone are particularly popular for fall and winter, while linen and cotton versions work for spring and summer.
