Whether you're the one getting married, or simply raising a glass to the happy couple, planning your spring or summer wedding attire ahead is essential—last-minute choices rarely deliver the perfect fit or style you're hoping for. Plus, early preparation gives you time to consider what the wedding party will (or might) wear, match accessories to the event's color scheme, and ensure your look aligns with the venue and formality level.
Speaking of formality—don't overlook this crucial factor in choosing the ideal summer wedding outfit. A casual backyard celebration demands a completely different approach than a black-tie evening wedding. And naturally, your role matters enormously: grooms should stand out as the most polished attendee, while guests need to dress appropriately without overshadowing the wedding party.
Let's dive into the perfect men's summer wedding attire options for 2025, organized by formality level and your specific role in the celebration.

Casual Summer Wedding Attire
For Grooms (Casual)
Brown Suit
A brown suit offers the perfect balance for men's casual summer wedding attire—distinctive enough to set you apart while remaining approachable and warm. It coordinates beautifully with a tan outfit for your wedding party, creating a cohesive yet hierarchical look where you remain the visual focal point. We recommend making it a three-piece ensemble to further distinguish the groom's outfit.
Brown is a true neutral, working seamlessly with both black accessories (our preference for a slightly more formal edge) and brown accessories for a softer, more relaxed aesthetic. The versatility makes it ideal for outdoor venues, garden parties, and daytime celebrations where the dress code doesn't demand extreme formality.

Light Blue Suit
For grooms who want to incorporate a bit more personality into their casual summer wedding outfits, a light blue suit delivers perfectly. This refreshing alternative to traditional neutrals brings a subtle pop of color that stands out beautifully in summer lighting and wedding photos.
To elevate this look slightly, add a matching light blue suit vest. The additional layer creates a more complete silhouette and adds formality without sacrificing the casual summer vibe. This option works especially well for beach weddings, where the color echoes the ocean backdrop, or for any groom whose personal style leans more expressive than traditional.

For Guests (Casual)
Light Grey Suit
A light grey suit is the guest's go-to at casual summer weddings. This color thoughtfully avoids the more common wedding party hues (navy, blue, black) while still looking appropriate and seasonally relevant. It's particularly flattering in natural light, making it ideal for daytime ceremonies and outdoor receptions.
Light grey functions as a chameleon, adapting beautifully to any wedding color scheme. It works equally well with black or brown shoes and can be dressed up or down with accessories depending on the specific formality level indicated on the invitation. This versatility makes it a smart investment for men's summer wedding attire that will serve you well beyond a single event.

Formal Summer Wedding Attire
For Grooms (Formal)
Navy Suit
For formal summer weddings that don't explicitly require a tuxedo, a navy blue suit delivers the perfect balance of tradition and seasonality. This timeless option projects authority and sophistication while coordinating seamlessly with blue attire for groomsmen, creating a cohesive yet distinguished wedding party aesthetic.
Navy particularly shines for evening ceremonies, which tend to skew more formal regardless of season. The deep, rich color maintains its elegance under artificial lighting while still feeling appropriate for the summer months. Add a matching suit vest to increase formality, or keep it as a two-piece for slightly more relaxed (but still formal) events.

Black Linen Tuxedo
When your summer wedding calls for black tie or black tie optional attire, our Shadow Black Linen tuxedo delivers the perfect combination of formality and summer-appropriate fabric. This exclusive option features an airy, breathable linen blend that maintains the sophisticated silhouette of traditional summer wedding attire while offering significantly improved comfort in warm weather.
The textured fabric adds subtle visual interest that distinguishes it from standard wool tuxedos, making it clear this choice was intentional rather than seasonal compromise. Pair with classic black patent leather shoes or loafers, and a proper bow tie.

Charcoal Suit
A charcoal suit gives guests attending formal summer weddings the perfect balance—slightly more serious than a medium grey option, yet not as severe as black. This sophisticated neutral serves as an excellent canvas for accessories that can be aligned with the wedding's color scheme.
The deeper tone helps you look polished and appropriate without competing for attention with the wedding party. It transitions beautifully from daytime ceremonies to evening receptions, making it particularly valuable for all-day celebrations. For summer weddings with a "cocktail attire" designation, charcoal hits exactly the right note for men's summer wedding attire.

Essential Black Tuxedo
For black tie optional or black tie summer weddings, our Essential Black Tuxedo is an ideal choice. While a charcoal outfit can suffice for black tie optional events, we still recommend a proper tuxedo when possible—it shows respect for the occasion and ensures you'll never feel underdressed.
Investing in a well-fitted black tuxedo means adding a versatile formal option to your wardrobe that will serve you for years beyond this specific wedding. Pair with traditional formal accessories: black patent leather shoes, a proper bow tie, and either a cummerbund or formal vest for complete summer wedding attire.

Summer Wedding Attire for Groomsmen
Groomsmen (Casual)
Grey Suit
For groomsmen at casual summer weddings, a grey suit provides maximum versatility. This neutral foundation complements virtually any groom's outfit choice while harmonizing with all wedding color schemes and themes. It can be styled up or down depending on the formality level, making it adaptable to everything from garden parties to vineyard celebrations.
Grey photographs beautifully in natural light, ensuring the wedding party looks cohesive and polished in all setting types. For a truly coordinated look, match the shade of grey to the overall color palette of the wedding, opting for lighter greys for daytime events and slightly deeper tones for evening celebrations.

Groomsmen (Formal)
Blue Suit
A blue ensemble strikes the perfect balance for groomsmen at formal summer weddings—structured enough to convey appropriate reverence for the occasion without being overly serious. It pairs exceptionally well with nearly any groom's attire choice while adding a subtle touch of personality to the wedding party.
If weather permits, adding matching blue vests creates a more formal three-piece look that will maintain its polish even when jackets inevitably come off during the reception. This option is particularly effective for wedding parties where you want a unified look that still allows for individual expression through accessories and styling details.

Peak Lapel Tuxedo
When the groom opts for black tie attire, groomsmen should follow suit with proper tuxedos. Our Peak Lapel Tuxedo represents the most classic and traditional formal option for men's summer wedding attire, featuring the distinctive angular lapels that have defined men's formalwear for generations.
The single-button closure creates a lean, elongated silhouette that flatters every body type while clearly communicating the event's formality. This traditional styling ensures wedding photos will remain timeless rather than tied to passing trends—an important consideration for images that will be treasured for decades to come.
