A cummerbund is a wide, pleated belt traditionally worn with a tuxedo during formal events as an alternative to a vest. Its name comes from the Persian “kamarband” which means “waistband.” Here is a step-by-step guide on how to wear a cummerbund correctly.

1. Pick the right cummerbund: Choose a cummerbund that matches or complements the color of your tuxedo, usually black, navy blue, or white. The material should match your bow tie, typically silk or satin.

2. Put on your dress shirt: Wear a wing-tip collar or turndown collar dress shirt that is specifically designed for tuxedos.

3. Button-up: Completely button the dress shirt and keep a polished look by ensuring that the dress shirt’s top button is fastened securely.

4. Adjust the waistband: Cummerbunds usually have an adjustable waistband at the back; ensure it is adequately adjusted to fit your waist comfortably.

5. Position the cummerbund: Position it around your waist with the pleats facing upwards. The top edge should rest just below your ribcage, and the lower edge should cover your waistband.

6. Secure the cummerbund: With adjustable straps or buckles located at the back of the cummerbund, secure it comfortably around your waist without it being too tight.

7. Check for evenness and alignment: Ensure that your cummerbund is centered and sits evenly on your waist with no twists or wrinkles.

8. Wear a bow tie: Attach your matching bow tie ensuring that it sits neatly between your collar points without any overlap with your collar.

9. Button your jacket: For single-breasted jackets, always keep the top button fastened when standing and undone while seated. For double-breasted jackets, always keep all buttons fastened.

10. Pocket square etiquette: If you opt for a pocket square, ensure its color and fabric coordinate with your cummerbund and bow tie but do not match them exactly. Fold the square neatly and place it in the jacket pocket so that only a small portion is visible.

11. Final touches: Do a last check in the mirror to ensure everything is positioned correctly and looking sharp before heading out into your formal event.

Following these 11 steps will help you wear a cummerbund with style and confidence, adding a touch of timeless elegance to your formal attire.
