Formal Occasions: When to Button Up

At formal events, it is expected that you keep your blazer buttoned. This rule applies to weddings, black-tie galas, and other such affairs where a tuxedo or dinner jacket is the order of the day. By remaining buttoned up, you are respecting the dress code and demonstrating an understanding of the protocol.

However, there are exceptions to this rule. If you find yourself retired to the smoking lounge or stepping outside for a breath of fresh air, it is perfectly acceptable to unbutton your blazer to facilitate movement and comfort.

For single-breasted blazers, the general rule of thumb is to button the top button only when standing. When seated, unbutton your blazer to avoid stressing the buttons and maintain a relaxed posture. This rule applies to blazers with one to three buttons.

As a word of caution, refrain from buttoning a single-breasted blazer with more than three buttons. The top button should align with your waistline when standing, and doing so with an excess of buttons can lead to discomfort and an unbalanced appearance.

Double-Breasted Blazers

Double-breasted blazers are a different beast altogether, with their grand statement and sartorial boldness. The rule dictates that you should keep all the buttons done up when standing, creating a streamlined silhouette. However, when seated, unbutton the outer row of buttons to preserve the blazer's shape and your comfort.

For double-breasted blazers with six buttons, it is acceptable to only button the top two or four, depending on your preference. This practice offers a modern take on the double-breasted blazer, but it is essential to strike a balance between style and tradition.

When the sun sets on formalities, and the casual hour approaches, the strict rules of blazer etiquette relax somewhat. During informal events or everyday wear, experts recommend keeping your blazer unbuttoned to project a relaxed, laid-back persona. This rule applies to blazers worn with jeans, chinos, or other casual attire.

However, there is a caveat to this seemingly relaxed rule. If your blazer has a defined waistband or is form-fitting, it is advisable to keep the top button fastened to maintain the blazer's structured silhouette. Conversely, larger, looser-fitting blazers can be left unbuttoned to avoid overwhelming your frame.
