Top Groomsmen Wedding Mistakes to Avoid

Serving as a groomsman is a big responsibility. Beyond just showing up in a suit, it’s your role to help the groom and ensure everything goes smoothly.

But some common mistakes can lead to awkward or stressful moments on the big day. Here are the top groomsmen wedding mistakes to avoid—and how you can be the best support for the groom.

1. Arriving Late

Arriving late is one of the most disruptive mistakes a groomsman can make. It puts extra pressure on the groom, the photographer, and anyone else waiting for the group. Running behind schedule may lead to missed moments and delays.

To avoid this, set multiple alarms, plan to arrive early, and confirm directions to the venue ahead of time. Even if others are running late, being on time ensures someone is there to help set things in motion.

2. Forgetting Essential Items

From cufflinks to boutonnieres, forgetting key items can throw off the wedding day attire. Small items are often overlooked, but missing even one can disrupt photos and the overall look of the wedding party.

Pack a small bag the night before with all the essentials, including any special items the groom has provided. Plan ahead and create a checklist of everything you need, and double-check it before leaving for the venue.

3. Being Unprepared for Speeches

If you’re expected to give a toast or speech, showing up unprepared can be nerve-wracking and might even lead to an embarrassing moment. Rambling or freezing up during a speech can take away from the joyful atmosphere.

Prepare your speech ahead of time, and practice it a few times so you feel confident. Keep it concise, positive, and appropriate. Avoid inside jokes or stories that could embarrass the groom.

4. Drinking Too Much

While a few drinks can help you relax, overindulging is a mistake that can lead to unprofessional or inappropriate behavior. Drinking too much can affect your ability to assist with tasks and reflect poorly on the groom.

Drink responsibly, pace yourself by drinking water between alcoholic beverages, and remember your responsibilities for the day. Keep the celebration respectful and focus on helping the groom.

5. Not Helping the Groom Stay Calm

Weddings can be stressful, and the groom may feel anxious as the day unfolds. One of your key roles is to be a calming presence and help the groom stay relaxed and composed.

Check in with the groom regularly, offering words of encouragement and handling any small issues that come up. Remind him to take a deep breath whenever he feels overwhelmed, and encourage him to focus on enjoying the moment.

6. Neglecting to Participate in Photos

Skipping out on photos or not being attentive during photo sessions is a common groomsman mistake. Not being in place or looking uninterested in photos can create chaos for the photographer and diminish the quality of memories captured.

Stay alert during photo sessions and follow the photographer’s guidance. Make an effort to be present and engaged to help the wedding photos turn out beautifully.

7. Ignoring Dress Code or Grooming Standards

The groom typically has a specific vision for the wedding suits, dress shoes, and overall aesthetic, which often aligns with the wedding budget. Ignoring the dress code or neglecting grooming can result in a fashion faux pas that disrupts the groom’s vision and makes you stand out negatively.

Ensure your suit jacket and dress shirt are clean and pressed, and follow any grooming instructions provided by the groom. If unsure about specifics, ask the groom or a fellow groomsman for guidance well before the wedding date so you have enough time to prepare.

8. Being Distracted During the Ceremony

Checking your phone or looking disengaged during the ceremony can be distracting and disrespectful. The ceremony is a formal and meaningful event, and a groomsman’s attention is part of the support the groom needs.

Turn off your phone and focus on the ceremony, supporting the groom and celebrating the couple’s vows. Stay mindful and attentive as a sign of respect.

9. Overstepping Boundaries with Guests

Whether it’s a flirtation or a disagreement, interacting with guests inappropriately can reflect poorly on the groom and disrupt the reception. Overstepping boundaries is a common but avoidable mistake. 

Be respectful and friendly with all guests, and avoid any actions that could lead to conflict or discomfort. If issues arise, handle them discreetly or involve wedding staff if necessary.

10. Forgetting Your Assigned Responsibilities

Groomsmen are often assigned tasks during the wedding planning, such as collecting gifts, assisting with transportation, or helping guests. Forgetting these responsibilities can lead to confusion and stress for the groom, his better half, and other members of the wedding party.

Create a list of your assigned tasks and check it periodically. Communicate with the best man or groom to stay on the same page and ensure all responsibilities are covered.

11. Not Practicing for the Dance

If the groom wants a coordinated dance or the wedding includes a first dance that involves the groomsmen, skipping out on practice can lead to mistakes on the dance floor. An unprepared performance can look sloppy and take away from the fun.

Attending rehearsals and practicing as needed is a great way to avoid this mistake. Focus on the steps and have fun—your enthusiasm will add to the celebration.

12. Focusing More on Socializing Than Supporting the Groom

Socializing with friends or family at the wedding is great, but it’s easy to get too caught up in the fun and forget the main purpose. Spending too much time socializing can mean you’re unavailable for the groom if he needs something.

Balance your socializing with time spent checking in on the groom and other groomsmen. Make sure you’re there to help when needed.

13. Not Preparing a Recovery Kit

Weddings are long events, and many things can go wrong—from minor cuts to wardrobe malfunctions. Failing to bring a few essentials can leave you or others in a tight spot if something unexpected occurs.

Pack a small recovery kit with bandages, mints, a lint roller, and any other useful items. This kit can be a lifesaver in case of minor issues.

14. Mismanaging Time During the Day

The wedding day moves quickly, and time management is crucial for keeping everything on schedule. Losing track of time can make the whole day feel rushed and unorganized.

Keep an eye on the time and stay aware of the schedule. Coordinate with the best man to ensure everyone is where they need to be when they need to be there.

15. Leaving Early Without Checking In

Leaving before confirming with the groom or best man that you’re no longer needed can cause unnecessary stress. Your presence might be required for late photos, final toasts, or helping to clean up.

Before leaving, check in with the groom or best man to ensure there’s nothing else they need. Offer a hand with any final duties to help wrap up the day smoothly.

16. Forgetting to Enjoy the Moment

Being a groomsman is an honor, but some groomsmen get so caught up in their responsibilities that they forget to have fun and enjoy the moment. This can lead to stress and a feeling of missing out.

Remember to be present and have fun. While staying responsible, allow yourself to celebrate and make the most of the special occasion.
