How to Choose the Perfect Wedding Suit for the Groom, Groomsmen & Guest

Weddings are one of the most important occasions in a person's life, and finding the right suit matters. Whether you’re the groom, an usher or guest selecting the right suit is crucial. With weddings ranging from formal to a more relaxed vibe, it can sometimes be tricky to pick a suit that matches the style of the day. At Marc Darcy, we believe every man deserves a suit that feels effortless and sharp as well as comfortable. 

With that in mind, we’ve pulled together a definitive guide to choose the perfect wedding suit for every role. 

The Groom: Stand Out Without Overpowering

The groom's suit sets the tone for the rest of the wedding party.

• Go for a subtle classic piece. Opt for a three-piece suit in a distinctive shade. Think stone, navy or tan with subtle texture for added class.
  

• Prioritise Fit. Your suit should look sharp and tailored to fit you like a glove. Size up and take it to a tailor to make personal tweaks to suit your body.
  

• Consider the wedding theme. Every wedding has a colour theme. Bring these shades into your look with subtle touches like your pocket square or tie.
  

• Fabric choice matters. Alongside fit, the fabric of choice is also crucial. Consider lightweight, flexible fabrics like Lycra blends for spring/summer months. And wool blend fabrics for the cooler months.
  

Marc Darcy tip: A classic navy or stone suit strikes the perfect balance of timeless style and groom-level presence.

Groomsmen: Cohesion with Personality

In 2026, we’re seeing more and more grooms experiment with suit choices for their groomsmen. 

• Match on tone, vary on style. Keep the colour palette consistent, but consider different pieces (two-piece vs three-piece) or mix and match (groom in a navy suit with a contrast waistcoat).
  

• Consider body types. Give groomsmen a choice of fit styles (regular, tailored, slim) so everyone feels comfortable.
  

• Accessories unify the look. Accessories are often overlooked, but they can be the finishing touch that pulls a look together. Ties, pocket squares and boutonnieres in complementary colours all work wonders in making the look cohesive.
  

Pro tip: Coordinated but not identical suits look great in group photos and add visual harmony without uniformity.

Wedding Guests: Dress for the Dress Code

As a wedding guest, your aim is to look polished and stylish without overpowering the wedding party and respecting the dress code. 

• Formal weddings: A formal dress code calls for a three-piece suit. Opt for classic navy or grey, style with a crisp white shirt and polished shoes.
  

• Semi-formal ceremonies: A more casual option, like a two-piece suit in a lighter, softer fabric, can help to strike the balance between dressy and comfortable.
  

• Outdoor or daytime weddings: Lean into breathable fabrics and softer shades; think pastels and earthy tones to complement the setting.
  

Friendly reminder: Avoid wearing white or very light neutrals that could be mistaken for bridal tones.

Styling Tips for Every Role

• Mix and match pieces. Mix and match is the perfect way to add personality to a look. A blazer worn with different trousers can work for both wedding and post-wedding events.
  

• Accessorise smartly. A patterned tie or classic leather watch adds personality and elegance.

• Footwear counts. The footwear you choose can make or break a look. Go for polished oxfords for formal dress codes, and loafers for casual smart dress codes.
