Dressing a group of groomsmen for October means planning for two kinds of weather in one day: a mild afternoon ceremony and a noticeably cooler evening. Navy, charcoal, brown, olive, burgundy and forest green all suit the month, and wool, flannel and tweed give real warmth outdoors. What separates a sharp wedding party from a merely matching one is coordination of the small things, shirt, tie, shoes, belt, pocket square and boutonniere, without everything looking stamped from the same mold. And every man needs his suit fitted, even when the whole group rents the same model. The outfits below cover ballrooms, hotels, barns, gardens and relaxed outdoor parties, with a note on each for setting the groom apart.
Six Different Builds in One Suit
A wedding party is rarely a set of matching body types. One man is tall and thin, another is broad through the chest, another is shorter with an athletic build. The same suit has to work on all of them, and these are the adjustments I make so the group still looks uniform.
- Jacket length: the jacket should cover the seat of the trousers on every man. On a tall groomsman, a regular length can look short, so order long sizes where needed.
- Trouser break: pick one break for the whole group, slight or none, and hem everyone to it. Mixed breaks are the most visible inconsistency in group photos.
- Sleeve length: the same small amount of shirt cuff should show on everyone, usually about a quarter to half an inch.
- Broad or muscular builds: let the waist out rather than sizing up the whole jacket, which leaves the shoulders hanging off.
- Larger groomsmen: a slightly longer jacket and a darker tie keep the line vertical and comfortable.
Lapel width and button stance come from the suit model, so choose one model for the whole party. Then fit each man individually.
1. Navy October Groomsmen Suit With Burgundy Tie
Navy wool is the suit I'd hand a group when the couple wants something classic that won't look too dark in daylight. A two-piece with a modern but forgiving fit suits most builds in a wedding party, which matters when the men range from slim to broad. Add a crisp white shirt and a burgundy silk or grenadine tie, dark brown Oxfords with a matching belt, dark socks, a white pocket square and a small boutonniere of greenery or muted red flowers. Hotels and garden venues suit it. For the groom, a navy three-piece, a patterned tie or a contrasting waistcoat keeps him connected but distinct.
2. Charcoal October Groomsmen Suit With Rust Tie
Charcoal with rust is the October pairing I find hardest to get wrong. A medium-weight wool suit with notch lapels, a white or soft ivory shirt and a matte rust tie brings in fall color without overpowering the gray. Matte is the important word; shiny rust looks orange in flash photos. Black Derbies and a black belt keep it formal, and dark brown shoes soften it for an outdoor venue. An ivory pocket square and a boutonniere with copper, cream or green finish it. Charcoal looks consistent in both daylight and indoor light. The groom can take a deeper tie, a charcoal waistcoat or a more distinctive boutonniere.
3. Forest Green October Groomsmen Suit With Tan Accessories
Forest green is a confident move for a wedding party, and it pays off at woodland ceremonies and rustic estates. Pair a solid green wool suit with a white spread-collar shirt and a tan or champagne tie, medium brown brogues, a matching belt and warm neutral socks. A cream pocket square and a plain greenery boutonniere stop it getting too colorful. The practical warning I give every group choosing green: order every suit at the same time from the same fabric run. Green dye varies more than navy or gray, and two slightly different greens side by side are obvious in photos. The groom can add a patterned waistcoat, a darker tie or an antique-style tie bar.
4. Chocolate Brown October Groomsmen Suit With Cream Shirt
Chocolate brown gives a wedding party warmth, especially when the palette around it includes beige, terracotta, sage or muted gold. I pair a structured brown suit with a cream shirt, which is softer against brown than bright white, plus a dark olive or taupe tie, brown cap-toe shoes, a matching belt, a cream linen pocket square and a green boutonniere. Brown suits some complexions better than others, so I always check a swatch against every groomsman's skin outdoors before ordering for the group. Historic estates and countryside venues suit it. The groom stands out in a brown three-piece or a deeper espresso tie.
5. Black October Groomsmen Tuxedo With Bow Tie
For an evening wedding, a classic black tuxedo for the whole party is the sharpest option. Each man wears a single-breasted tux with satin or grosgrain lapels, matching trousers, a white formal shirt, a black bow tie, polished black Oxfords, black socks and a white pocket square. Rental tuxedos often come in slightly different lapel styles and shirt fronts, so I make sure the whole group gets the same model and the same shirt. Mismatched pleats show in every group photo. Keep boutonnieres compact so they don't break the lapel line. The groom can wear a peak lapel, a waistcoat, special cuff links or a slightly larger white boutonniere.
6. Burgundy October Groomsmen Suit With Black Accessories
Burgundy suits make a wedding party look bold, and they need careful balancing. A crisp white shirt, a black silk tie, a black belt, polished black Derbies and dark socks keep the line clean. Then just a plain white pocket square and a small cream and green boutonniere; another strong color fights the suit. I always order swatches first, because burgundy can look red, purple or brown depending on the light, and what reads as wine in a shop can look maroon under warm reception lighting. Contemporary indoor venues with neutral decor suit it. The groom can wear a black tuxedo or a deeper burgundy three-piece.
7. Olive October Groomsmen Suit With Brown Shoes
Olive looks relaxed, which is exactly why every detail has to be coordinated or it slides toward casual. Start with a tailored olive wool suit and a white or pale beige shirt, then a dark brown knit tie for texture, brown Derbies, a matching belt and brown or olive socks. A cream pocket square and a boutonniere of greenery with one small neutral flower keep it clean. Daytime ceremonies, gardens and barns suit it. Too many other earth tones around it start to look like hunting gear, so I keep the rest of the palette simple. The groom can wear a waistcoat, a patterned tie or a darker olive suit.
8. Brown Tweed October Groomsmen Suit With Knit Tie
Tweed belongs at a crisp countryside wedding. I'd choose brown or brown-gray tweed with a tailored jacket and straight, lightly tapered trousers, worn with a white shirt and a solid burgundy, forest green or navy knit tie. Dark brown brogues, matching belts and thicker dress socks suit the weight of the cloth. Add an ivory pocket square and a small boutonniere of greenery or dried-looking seasonal textures. The catch with tweed is heat. A heated barn full of dancing groomsmen in heavy tweed gets uncomfortable fast, so pick a moderate weight and skip extra layers indoors. The groom can add a matching waistcoat or a subtle windowpane.
9. Midnight Blue October Groomsmen Three-Piece Suit
Midnight blue three-piece suits give a wedding party a formal look without going all the way to black tuxedos. Midnight blue also tends to look richer than black under warm evening light. Style the jacket, trousers and waistcoat with a white shirt and a silver-gray or muted blue tie, black Oxfords, a black belt, dark navy socks and a white pocket square, with a simple white and dark green boutonniere. I reach for it when a late-afternoon ceremony runs into an evening reception. The waistcoats keep the group looking finished once jackets come off for dinner. For the groom: a peak lapel, a patterned tie, a pocket watch or a contrasting waistcoat.
10. Camel October Groomsmen Suit With Chocolate Tie
Not every October wedding needs dark suits. In a warm climate or at a bright daytime ceremony, camel is a good lighter option. Pair it with a white or cream shirt and a chocolate brown tie, dark brown loafers or Derbies, a matching belt and medium brown socks, plus an ivory pocket square and a greenery boutonniere with rust or cream accents. I insist on a matte camel cloth; shiny camel looks cheap in photos and shows sweat marks in the sun. Modern gardens and bright event spaces suit it. The groom can wear a chocolate suit or a camel three-piece.
11. Gray Flannel October Groomsmen Suit With Sage Tie
Gray flannel gives a wedding party warmth and a soft texture that looks great up close. Choose medium gray rather than pale, with a clean white shirt and a muted sage tie, dark brown Oxfords, matching belts and charcoal socks, a white pocket square and a greenery boutonniere with one small cream flower. It goes well with sage, ivory, dusty blue and neutral palettes. Flannel has a soft, slightly fuzzy surface and more bulk than worsted, so tailoring is essential; an unaltered flannel jacket on a slim man looks boxy. The groom can wear charcoal flannel, add a waistcoat or take a patterned sage tie.
12. Navy October Groomsmen Suit With Burnt Orange Tie
Burnt orange on navy is pure October, as long as it's used with restraint. Matching navy wool suits and white shirts are the base, with matte burnt orange ties, dark brown shoes and belts, and dark socks so the trouser line runs straight into the shoe. White pocket squares and small boutonnieres with greenery, cream flowers and a hint of orange finish it. I stop the orange at the tie. Matching socks, pocket squares and flowers to it as well makes the group look like a team kit. Barns and outdoor estates suit it. The groom might wear a navy three-piece with a burgundy tie or a patterned orange pocket square.
13. Black October Groomsmen Suit With Emerald Tie
Black suits with emerald ties make a clean, dramatic wedding party for a formal evening. Choose matte black two-piece suits with well-proportioned lapels, bright white shirts, deep emerald ties, polished black Oxfords, black belts and black socks, plus white pocket squares and small green and white boutonnieres. If the men are buying their own black suits, check them side by side. Black from different makers and fabrics varies from blue-black to brown-black, and it shows clearly in group photos. Modern hotels, lofts and galleries suit it. The groom can wear a black three-piece, a tuxedo or an emerald velvet dinner jacket.
14. Plaid October Groomsmen Suit With Solid Accessories
A subtle plaid gives a wedding party interest without losing polish. I look for charcoal, navy or brown with a restrained windowpane or small check; a big bold plaid on six men at once is overwhelming. Pair it with a solid white shirt and a plain tie in burgundy, navy, forest green or taupe. Choose dark brown or black shoes depending on the suit's base color and match the belts. Solid pocket squares and simple boutonnieres keep the pattern in check. Historic venues and upscale barns suit it. The groom can wear the same plaid as a three-piece, or a solid suit in one of the check's secondary colors.
15. October Groomsmen Separates With Suspenders And Bow Ties
For a relaxed October wedding, coordinated separates can replace full suits entirely. The groomsmen wear white shirts, charcoal or brown wool trousers, textured suspenders and matching burgundy or forest green bow ties, with brown brogues and thicker neutral socks. A belt and suspenders together is a mistake I correct often; add belts only if the suspenders come off. A tweed or wool blazer for the ceremony gives everyone a layer if the evening turns cold. Keep pocket squares and boutonnieres identical to unify the group. It suits casual barns and daytime outdoor celebrations, not ballrooms. The groom can wear a full three-piece in the same trouser color.
Renting, Buying and the Groomsman Who Lives Far Away
Renting suits the group when the outfit is a tuxedo or an unusual color nobody will wear again. Buying makes more sense for navy, charcoal or gray, which every man can reuse. Either way, start early. I'd collect measurements around three months out and place the order soon after.
Out-of-town groomsmen are where things go wrong. Have each one measured professionally rather than with a tape at home, and plan a try-on as soon as he arrives, ideally two or three days before the wedding, not the morning of. That leaves time for a quick hem or a size exchange.
Making the Group Match on the Morning
- Agree on one tie knot. A four-in-hand next to a full Windsor looks uneven in a line.
- Tie tips should all land at the top of the belt buckle.
- Fold every pocket square the same way, and have one person do them all if needed.
- Pin boutonnieres on the left lapel, at the same height, stem pointing down.
- Check socks. One pair of white athletic socks shows up in every seated photo.
- Leave the top jacket button fastened when standing and undo it to sit.
Coordinated Without Looking Identical
Good groomsmen outfits come down to seasonal color, the right formality, comfortable cloth and consistent coordination. Navy and charcoal are dependable; forest green, brown, olive, burgundy and camel make a stronger autumn statement. Tuxedos suit formal evening weddings, and tweed, flannel or separates feel right at rustic venues. Once the suit is chosen, standardize the shirts, shoes, ties, pocket squares and boutonnieres, and make sure every man gets his own alterations rather than one size that fits nobody. Then give the groom one or two details of his own, a waistcoat, a different tie or a more formal jacket, so the group reads as a team with a clear leader.
