Introduction
When it comes to wearing a suit, the way you button your jacket might seem like a small detail—but trust us, it makes a big difference. Whether you’re heading to a job interview, a formal event, or just leveling up your daily style, knowing the proper way to button a suit jacket shows you pay attention to the details. And that, gentlemen, is what style is all about.
In this quick guide, we’ll break down the do’s and don’ts of suit buttoning so you can step out with confidence, class, and yes—correct buttons.

Why Suit Buttoning Matters
Before we jump into rules, let’s talk about why this even matters.
Suit jackets are designed with specific structure and drape in mind. Buttoning them correctly preserves their shape, flatters your body, and communicates style awareness. Button incorrectly, and the whole fit may appear off—too tight, too loose, or just plain awkward.
Let’s get you sorted.
The Golden Rule for Single-Breasted Jackets
Most modern suits are single-breasted with either two or three buttons. Here’s how to master each:
Two-Button Jacket
- Top button:Always button it.
- Bottom button: Never button it
Why?The bottom button is purely decorative. Fastening it disrupts the jacket’s natural flow and can make it bunch up or pull oddly.

Remember: Always – sometimes – never doesn’t apply here. It’s simply: Always / Never.
Three-Button Jacket
- Top button:Sometimes.
- Middle button:Always.
- Bottom button:Never.
This gives you the classic “Sometimes – Always – Never” rule.
Pro tip: If you’re on the shorter side, skip the top button. It can visually shorten your torso.

Double-Breasted Jackets: A Bit More Formal
Double-breasted jackets are bold, structured, and always buttoned a bit differently.
- Anchor button (inner):Always fasten it—it keeps the jacket sitting properly.
- Main outside buttons: Always button the top; leave the bottom undone.
You’ll rarely (if ever) unbutton a double-breasted jacket, even when sitting. It’s designed to stay closed.

Should You Unbutton When Sitting
- Yes—for single-breasted jackets. Always unbutton your jacket when you sit down to avoid creasing and straining the fabric. It’s also more comfortable.
- No—for double-breasted jackets. These are structured to remain buttoned.
Bonus Tips for Buttoning Like a Pro
- Fit comes first: Even perfect buttoning can’t save a poorly tailored jacket. Invest in good tailoring.
- Keep posture in mind: Buttoning your jacket encourages better posture, which enhances your overall look.
- Use buttoning as a style cue: Unbuttoning the jacket while moving or sitting adds a casual, relaxed vibe—just rebutton when you stand.
Conclusion
Buttoning your suit jacket properly is one of the easiest ways to elevate your look—and one of the most overlooked. Follow these timeless rules and you’ll not only look sharper but feel more confident. It’s not just about fashion—it’s about carrying yourself with intention.
So next time you suit up, remember: it’s the little things that separate the good from the great.
