What Should the Groom's Dad Wear? A Complete Guide for Fathers of the Groom

You’ve got the tuxedo sorted. The best man knows his role. But then there’s the elephant in the room: what on earth is your father supposed to wear? It’s a question that causes more panic than you’d think. One minute he’s wearing his old work blazer, the next he’s stressing about whether black tie means a bow tie or if he can get away with a navy suit. Don’t worry. Getting it right isn’t about matching everyone perfectly; it’s about looking sharp, feeling comfortable, and respecting the couple’s vision without upstaging the groom.

Decoding the Dress Code Clues

Before you head to the tailor, you need to know what the invitation actually says. Wedding dress codes aren’t just suggestions; they are strict rules that dictate fabric weight, color palette, and formality levels. If you guess wrong, you’ll either look like you’re going to a board meeting or a beach barbecue, neither of which fits a wedding vibe.

• Black Tie: This is non-negotiable. A Tuxedo is required, featuring satin lapels, a bow tie, and formal trousers. No exceptions. If you don’t own one, rent it. Do not show up in a regular business suit.
• Formal / Black Tie Optional: You have wiggle room here. A dark Suit in charcoal, midnight blue, or black works well, paired with a conservative tie. A tuxedo is acceptable but not mandatory. This is the most common code for evening weddings.
• Semi-Formal / Cocktail: Think lighter fabrics and colors. A mid-grey or navy suit is perfect. You can skip the tie if the venue is outdoors or casual, but keep the shirt crisp. A pocket square adds a nice touch of personality.
• Daytime Formal: Often seen in garden weddings. Lighter shades like tan, light grey, or pale blue are appropriate. Avoid heavy wools; opt for linen blends or tropical wool to stay cool.

The Golden Rule: Coordinate, Don’t Match

Here is where most dads go wrong. They hear "coordinate" and think "match." So they buy the exact same suit as the groom. Big mistake. If you look identical to the groom, you become part of the furniture rather than a distinguished guest. The goal is harmony, not uniformity.

A good rule of thumb is to follow the groom’s lead on formality but differ in shade or texture. If the groom wears a black tuxedo, you might wear a dark charcoal suit with a subtle pattern. If the groom wears a light beige suit for a summer wedding, you could wear a medium grey suit. This visual distinction helps photographers capture clear shots and ensures guests know who is who.

Choosing the Right Suit Color and Fabric

Once you know the dress code, pick your weapon. For most weddings, a Navy Blue Suit is the most versatile option, suitable for both day and evening events across all seasons. It photographs beautifully, hides stains better than light colors, and looks modern without being flashy. Charcoal grey is the runner-up, offering a slightly more serious, authoritative look.

Consider the season. In Melbourne, where we live, weather can change fast. If your wedding is in November, spring is in full swing. Temperatures might hover around 15-20°C. A heavy three-piece wool suit might make you sweat under the jacket. Look for "tropical wool" or high-twist fabrics that breathe. If the wedding is in January, summer heat demands linen or cotton blends, but beware: linen wrinkles easily. Bring a travel steamer or have it pressed right before the event.

Patterns are tricky. Solid colors are safest. If you want to add interest, choose a subtle windowpane check or a faint pinstripe. Avoid loud plaids or bold checks unless the wedding has a very specific rustic theme. Remember, you want to look timeless, not trendy. Trends fade; classic tailoring lasts forever.

Shirts, Ties, and Accessories That Matter

Your suit is the canvas, but the details are the paint. Start with the shirt. White is always correct. A light blue shirt can soften the look for daytime events, but avoid bright blues or pastels that clash with the bridal party’s palette. Ensure the collar fits properly-you should be able to fit one finger between your neck and the collar. Too tight, and you’ll feel choked; too loose, and it looks sloppy.

Ties are where you can show some personality. If the groom wears a solid tie, you might choose a subtle pattern like a small dot or diagonal stripe. Keep it conservative. Avoid novelty ties with cartoon characters or loud logos. A Pocket Square is an essential accessory that adds polish without requiring extra effort, folded simply in a presidential fold for maximum elegance. Match it to your tie or the groom’s boutonniere, but don’t match it exactly to your tie color. Contrast is key.

Footwear completes the look. Black oxfords are standard for formal events. Brown brogues work well for semi-formal or daytime weddings. Make sure your shoes are polished. Scuffed shoes ruin an otherwise perfect outfit. Also, break them in before the big day. New shoes cause blisters, and no one wants to see the father of the groom limping down the aisle.

Common Mistakes to Avoid

We’ve seen dads make the same errors over and over. Here’s how to dodge them.

1. Wearing the Wrong Shade of Grey: Not all greys are created equal. Light grey suits can look washed out in photos if the lighting is poor. Stick to mid-to-dark greys for reliability.
2. Ignoring the Bride’s Family: If the mother of the bride is wearing a floor-length gown, you shouldn’t wear shorts and loafers. Discuss the overall aesthetic with the couple to ensure balance.
3. Over-accessorizing: More is not more. A watch, a ring, and a simple bracelet are enough. Skip the multiple cufflink sets or flashy jewelry. Let the suit speak for itself.
4. Forgetting Comfort: You’ll be standing, hugging, and dancing for hours. If your suit pinches your arms when you raise them, it’s too tight. Tailoring adjustments cost little but save your dignity.

Final Checklist Before the Big Day

Do this two weeks before the wedding. Try on the full outfit. Sit down, stand up, raise your arms. Check the mirror from different angles. Take a photo in natural light. Does it look balanced? Is the hem length right? Trouser breaks should just touch the top of your shoe. No bunching, no floating.

If you’re renting, book early. Rental shops get busy during peak wedding season. Ask for a fitting appointment. They can adjust the waist and sleeve lengths on the spot. Buy your socks and underwear specifically for the occasion-dark, invisible socks prevent awkward skin flashes when you sit down.

At the end of the day, confidence is your best accessory. If you feel good in what you’re wearing, it shows. Talk to your son. Ask him what he envisions. Most grooms appreciate their fathers taking the time to get it right. It’s a gesture of respect and love, wrapped in fine wool and silk.
