A groom getting married in October has more room to play than one getting married in June. Heavier cloth looks natural, darker color suddenly makes sense, and a waistcoat earns its place by keeping him warm between the ceremony and the photos. When I start with a groom, I don't open with color. I ask about the dress code, the venue and whether he'll be standing outside, then I build the suit to suit those answers. The fifteen looks below cover formal tuxedos, rustic three-piece suits and relaxed separates, and each one is spelled out down to the shoes and the boutonniere.
Settle the Dress Code Before the Color
Half the grooms I talk to start with a color they love and then try to make it fit the invitation. It goes much more smoothly the other way around. The dress code narrows the list before you ever look at a swatch.
- Black tie: a tuxedo or a dinner jacket in black, midnight navy, ivory or velvet, worn with a bow tie. Suits don't belong here.
- Formal: a dark suit, usually charcoal, navy or a deep brown, with a tie. A tuxedo is welcome but not required.
- Semi-formal or cocktail: any of the colored suits on this list, plaid included, with a tie.
- Casual or rustic: separates, tweed blazers, Western suits and turtlenecks all make sense, but the groom should still be the best-dressed man there.
Time of day matters as well. Tuxedos are traditionally evening wear, so a two o'clock ceremony on a farm is better served by a suit, however formal the rest of the day feels.
1. Burgundy Wool Groom Suit
Burgundy is a confident choice that still reads grown-up, as long as the shade is right. I push grooms toward deep wine or oxblood and away from anything close to true red, which can look like a costume next to orange leaves. A crisp white shirt and a charcoal or black tie keep it serious; a muted floral tie softens it. Add the matching vest for warmth and for a more formal finish. Dark brown or black Oxfords both work, with a belt that matches the shoes and a cream pocket square. A boutonniere of greenery with small rust blooms ties him to the season. I'd keep this to late September through November, when the light and the leaves are on its side.
2. Forest Green Groom Suit
Forest green is the color I suggest most often to grooms who want something other than navy and are nervous about it. It turns out to be very wearable. Go for a dark, muted green in wool or a wool blend, then soften the contrast with an ivory shirt rather than stark white. A brown knit tie gives it texture; a quiet patterned tie works too. Dark brown Derby shoes, a matching belt and a folded cream pocket square complete it, and a waistcoat with a plain gold tie bar raises the formality. If he's in green, I'd put the groomsmen in charcoal or tan so he stays the focus. It sits naturally in a garden, a mountain lodge or a barn.
3. Navy Three-Piece Groom Suit
A navy three-piece is the safest bet on this list, and I don't mean that as a criticism. Choose a medium-weight wool in a navy that actually reads blue on camera, because the very darkest navies can look black in photos. Wear the jacket and vest over a white spread-collar shirt, then bring the season in through the tie: burgundy, rust or forest green. Brown cap-toe shoes and a matching belt keep it warm, while a white pocket square keeps it formal. The vest pays for itself at the reception. Once the jacket comes off, he still looks dressed rather than half-undressed. It suits barns, historic venues, country clubs and hotels equally well.
4. Charcoal Flannel Groom Suit
November weather is where flannel earns its reputation. Charcoal flannel has a soft brushed surface that looks richer than standard business suiting and feels warmer the moment you put it on. I'd style it with a white or pale blue shirt and a dark burgundy grenadine tie, whose open weave gives a little texture without pattern. Black Oxfords make it formal; dark brown brogues relax it. For an outdoor ceremony, add the waistcoat, a white pocket square and a seasonal boutonniere. Flannel is a thicker cloth, so fit matters more than usual. It should sit close without pulling at the chest button or across the thighs when he sits down. City venues and historic buildings suit it best.
5. Brown Tweed Groom Suit
Tweed is all about texture, which makes it the natural choice for a farm or countryside wedding. My advice is to stay with a refined herringbone or a solid tweed. Big heritage checks look great on a hanger and busy in a photo. Pair it with an ivory shirt and a rust knit tie, and add a brown waistcoat if the suit didn't come as a three-piece. Dark brown brogues or leather lace-up boots give it a sturdy finish. Keep the rest simple: a cream pocket square, antique-style cufflinks and a small greenery boutonniere. Because tweed is visually heavy, a crisp shirt collar and precise tailoring at the shoulder keep it from looking like a hunting jacket.
6. Tan Groom Suit With Rust Tie
Early September is tricky. It is technically fall, but the afternoon can still feel like summer. A tan suit in wool or brushed cotton with a rust tie handles that well. Start with a white shirt and choose a textured tie in rust or cinnamon; a glossy silk tie in that color looks cheap fast. Dark brown loafers or cap-toe shoes, a matching belt and a cream pocket square give the lighter suit some weight at the edges. A tan waistcoat adds definition, or he can stay in two pieces for a relaxed ceremony. A boutonniere of dried grasses and foliage suits the palette. Brushed cotton creases more than wool, so I'd expect some wrinkling by evening and accept it.
7. Black Tuxedo Groom Outfit
Nothing beats a black tuxedo for a formal evening wedding, and a crisp fall night is when it looks its best. I choose a dinner jacket with satin peak lapels, matching tuxedo trousers with the satin side stripe, and a formal white shirt. A black silk bow tie, black patent shoes and dark dress socks keep the black-tie foundation correct. Simple cufflinks, a folded white pocket square and a small white boutonniere are all the extras it needs. He can wear a low-cut black waistcoat for warmth or a cummerbund if the room will be hot; either covers the waistband. Resist the urge to add autumn color here. The strength of a tuxedo is its restraint.
8. Emerald Velvet Groom Jacket
An emerald velvet dinner jacket is the most romantic option on this list, and also the one that demands the most discipline elsewhere. Pair it with black tuxedo trousers so the green stays the focus. A white shirt, pleated or plain, a black bow tie and polished black loafers or patent Oxfords complete it. Keep the pocket square white and the boutonniere to one cream bloom or a sprig of dark greenery. A shawl or peak lapel both suit velvet. The thing I check most carefully is fit through the back and shoulders, since velvet shows every wrinkle and drag line. It is a warm fabric, so I'd keep it to indoor evening ceremonies in heated rooms.
9. Plaid Groom Suit
A subtle plaid gives a groom some personality without moving away from a refined look. I'd choose a charcoal, brown or navy base with a fine windowpane or muted check. Multicolored tartans are a different conversation. Pair it with a plain white shirt and a solid tie in burgundy, chocolate or forest green. A solid waistcoat breaks up the pattern and adds warmth. Dark brown shoes, a matching belt and a plain pocket square finish it, and the boutonniere should stay small so it isn't fighting the cloth. Small patterns can shimmer on camera, so I always ask to see a photo of the fabric from a few feet away before committing. Rustic estates and modern barns suit it best.
10. Olive Green Groom Suit
Olive is softer and more modern than forest green, and it plays well with a wedding palette of terracotta, beige, copper or dusty rose. I'd choose a muted olive wool with a structured jacket and tapered trousers. A white or light beige shirt keeps it fresh, and a chocolate tie gives it depth. Dark brown loafers or Derbies, matching socks and a coordinating belt ground it. A patterned pocket square can add a little personality, but keep its colors quiet. Cream flowers with greenery make the boutonniere. One caution: olive can turn sallow on very fair men with cool undertones, so I'd test the color near his face in daylight before ordering. Vineyards, greenhouses and gardens are its natural home.
11. Chocolate Brown Double-Breasted Groom Suit
A chocolate double-breasted suit gets its presence from color and shape, so the accessories can stay quiet. Choose a rich solid brown in medium-weight wool, with peak lapels and a defined waist. An ivory shirt and a dark brown or muted gold tie keep it tonal, and matching trousers give one long, unbroken line. Very dark brown Oxfords sit well under it. Add a cream pocket square, understated cufflinks and a small ivory and green boutonniere. Skip the vest; double-breasted jackets already cover the torso and a waistcoat underneath just adds heat. I'd also skip busy patterns. Double-breasted flatters taller grooms most, and it looks its best on formal October and November weddings.
12. Gray Groom Suit With Black Turtleneck
For a modern wedding, a fine-knit black turtleneck can replace the shirt and tie entirely. Pair it with a medium or dark gray wool suit with clean lines and little detailing. The knit has to be thin. Merino or a fine cotton knit sits flat under the jacket, while anything chunky bunches at the collar and makes the jacket look small. Polished black loafers, a black belt and dark socks complete it, and a plain silver watch and white boutonniere are enough decoration. I'd only recommend this if it genuinely fits the couple and the dress code allows it. At a formal or black-tie wedding, it will read as underdressed. City lofts, galleries and courthouse ceremonies suit it well.
13. Tweed Blazer And Chino Groom Outfit
Not every fall wedding needs a full suit. For a casual backyard or orchard ceremony, I like a fitted brown tweed blazer over tailored chinos in stone, khaki or dark olive. A white Oxford shirt and a textured burgundy tie give it definition, and a wool waistcoat separates the groom from guests who might be dressed similarly. Dark brown brogues or clean leather Chelsea boots, a matching belt and patterned dress socks finish it, with a cream pocket square and a greenery boutonniere. The chinos need to be pressed and properly hemmed, or the whole look slides from relaxed to careless. Skip distressed trousers, denim and chunky outdoor boots.
14. Western Groom Suit With Cowboy Boots
A Western groom can look polished as long as every piece is chosen with restraint. Start with a tailored charcoal, brown or navy suit and a crisp white shirt. A textured tie or a bolo that matches the wedding palette goes at the collar. Choose clean, polished cowboy boots with a streamlined toe, and have the trousers hemmed with the boots on; boot-cut trousers need a longer hem so they fall over the shaft without bunching. A leather belt with a modest buckle keeps it cohesive. A felt hat works for portraits and outdoor ceremonies, though it comes off indoors. A simple pocket square and a compact boutonniere finish it. It belongs at ranches, lodges and genuinely Western weddings.
15. Cream Dinner Jacket Groom Outfit
A cream dinner jacket is an elegant alternative for an early-fall or formal indoor wedding, especially when a full black tuxedo feels predictable. Pair it with black tuxedo trousers, a white formal shirt and a black silk bow tie. Black patent Oxfords or velvet loafers keep it evening-appropriate, and a white pocket square repeats the jacket's clean tone. The fabric matters more than people expect: I'd look for substantial wool or a textured dinner-jacket cloth, since summer linen looks out of season by October and wrinkles quickly. Black peak or shawl lapels connect the jacket to the trousers. Understated cufflinks and a small dark green boutonniere complete it.
A Topcoat for Outdoor Portraits
Fall portraits often happen outdoors as the sun drops, and that is when grooms start shivering. A topcoat solves it and photographs far better than a puffer jacket borrowed from a groomsman.
I'd choose a single-breasted wool overcoat that ends at or just above the knee, long enough to cover the suit jacket completely. Camel works over brown, olive and navy. Charcoal or navy works over nearly everything, including tuxedos. Make sure the coat is sized with the suit jacket underneath, since a coat bought to fit over a sweater will often be too tight across the back. A plain wool or cashmere scarf in a neutral color is the only other layer I'd add. For the ceremony itself, most grooms take the coat off, so the suit needs to handle the cold for twenty minutes on its own.
Standing Next to Her Dress
In nearly every photo, the groom stands beside the bride, so the shirt and boutonniere should agree with her gown. If her dress is ivory or champagne, a bright white shirt can make it look yellowed by comparison; an ivory or soft white shirt avoids that. If her dress is bright white, his shirt can be bright white too.
The boutonniere is the easiest link between the two outfits. Take one flower or a sprig of greenery from her bouquet, rather than inventing a separate arrangement. A tie that echoes the bridesmaids' color does a similar job, though I'd keep it a shade deeper so it doesn't look like a uniform.
Fit First, Then Fabric, Then Color
The right fall groom outfit pairs seasonal character with the correct level of formality. Burgundy, forest green, chocolate, navy and charcoal bring depth, and wool, tweed, flannel and velvet bring texture and warmth. But none of it rescues a suit that doesn't fit. A groom looks most confident in a jacket that sits cleanly across the shoulders, trousers that fall smoothly, and enough room to move, hug and dance. Shoes, ties, pocket squares and boutonnieres should support the suit, not compete with it. If I had to give one piece of advice, it would be to book the tailor before you fall in love with a color.
