October is the month when grooms can finally wear cloth with some substance. Midweight wool, flannel, tweed and velvet all make sense once the air cools, and the seasonal colors, forest green, burgundy, brown, charcoal and navy, look rich without tipping into costume. When I dress a groom, I start with the dress code and the venue, then work out how he'll stand apart from his groomsmen without clashing with them. Shoes, ties, pocket squares and the boutonniere tie it all together, and they're where most of the small mistakes happen.
Here are fifteen groom outfits I'd put together for an autumn wedding, from strict black tie to relaxed barn ceremonies, each worked out from shoes to lapel.
Cloth Weight Matters More in October Than Color
The color gets all the attention, but the weight of the cloth decides whether the groom is comfortable. Suiting is usually described by weight per yard, and a few broad bands cover most of what you'll see.
- Lightweight or tropical wool: made for summer and warm climates. Fine for a hot October destination, but it can wrinkle and feel thin outdoors in the evening.
- Midweight worsted wool: the year-round middle ground and my default for an October suit. Breathable indoors, warm enough for a short spell outside.
- Flannel and tweed: heavier, softer and genuinely warm. Ideal for an outdoor ceremony on a cold day, but they can run hot on a busy dance floor.
Ask for a swatch and hold it to the light. A cloth you can see through clearly is lighter than it looks in the catalog. And if the ceremony is outside and the reception indoors, choose for the reception; a good overcoat solves the cold part far more easily than you can cool down in heavy tweed.
1. Black Tuxedo Groom Attire
For a formal October evening, the black wool tuxedo is still the benchmark. Satin peak lapels, a crisp white French-cuff shirt and trousers with a satin side stripe set the frame, and a self-tie black silk bow tie looks noticeably better than a pre-tied one in close-up photos. Patent oxfords, black socks, understated cuff links and a white pocket square in a straight presidential fold finish it. A small boutonniere can bring in burgundy or greenery. Fit is what makes or breaks a tux: I check that the collar sits against the shirt collar with no gap and that the shoulder ends where his shoulder does.
2. Midnight Navy Tuxedo Groom Attire
Midnight navy reads richer than black under warm evening lighting, and in photos it holds detail where black can go flat. I'd pair a deep navy jacket with black satin lapels and matching navy trousers. A white tuxedo shirt, black bow tie and black suspenders keep it formal; suspenders also hold trousers at the natural waist so they hang cleanly. Polished black oxfords or loafers, silver cuff links and a white linen pocket square finish it, with white flowers and dark greenery on the lapel. Put the groomsmen in black and the groom in midnight navy, and he stands out without anyone looking mismatched.
3. Charcoal Three-Piece Suit Groom Attire
The three-piece charcoal suit is the most practical groom outfit on this list. The waistcoat keeps him warm on a cool evening and keeps him looking finished once the jacket comes off for dancing, which it always does. Choose midweight wool, a white spread-collar shirt and one tie in burgundy, forest green or a muted floral. Black cap-toe oxfords are the formal choice; dark brown brogues soften it for daytime. When the groomsmen wear two-piece suits, the waistcoat alone marks the groom. Make sure the waistcoat covers the trouser waistband with no shirt showing between them, a detail tailors get wrong more often than you'd expect.
4. Forest Green Suit Groom Attire
Forest green brings real autumn color into a groom's outfit and still reads as a serious suit. Dark green wool or a wool blend with a fitted jacket and tapered trousers is what I'd look for. A white or soft ivory shirt lifts the darker shade, and a black knit tie or a dark floral tie bridges it to the rest of the outfit. Dark brown oxfords, a matching belt and brown socks suit green far better than black shoes, which look harsh against it. A cream pocket square and a boutonniere of neutral flowers keep it from feeling heavy. It looks especially good against stone, timber and turning leaves.
5. Burgundy Suit Groom Attire
Burgundy is celebratory, but the shade matters. I steer grooms toward a deep, muted burgundy; a bright wine red looks like a stage costume in daylight. A crisp white shirt balances it, a black tie gives it a formal edge and a textured charcoal or navy tie softens it. Black oxfords, a black belt and dark socks ground the bold suit. Keep the pocket square white and the boutonniere simple greenery so the outfit doesn't get busy. The cleanest way to coordinate is groomsmen in charcoal or navy with burgundy ties, so the groom's full burgundy suit links to them without blending in.
6. Brown Tweed Three-Piece Groom Attire
Tweed is the most rustic option here and one of the warmest. A three-piece in chocolate, tobacco or brown herringbone suits a barn, a country house or a woodland ceremony in the daytime; it isn't right for strict black tie. Wear it with a white or pale blue shirt and a wool tie in burgundy, mustard or dark green. Brown brogues are the natural partner, since their punched detailing matches the texture of the cloth. Keep the watch, belt and pocket square simple because tweed already has a busy surface. One warning: heavier tweeds get hot indoors once the dancing starts, so the waistcoat matters for the jacket-off part of the night.
7. Chocolate Brown Suit Groom Attire
Smooth chocolate wool gives you autumn warmth without the country feel of tweed. Look for a deep espresso or cocoa shade and pair it with a white shirt, which gives clear contrast near the face; brown against brown at the collar can look muddy. A burnt orange, olive or burgundy tie links the outfit to the flowers. Dark brown wholecuts or cap-toes and matching socks keep the line unbroken from trouser hem to shoe. Finish with a cream pocket square, gold-tone cuff links and a restrained boutonniere. Groomsmen in tan, olive or lighter brown sit well next to it.
8. Navy Suit With Burgundy Tie Groom Attire
Navy with burgundy accessories is the combination I recommend most often to grooms who aren't sure, because it suits almost every skin tone and every October palette. Choose a mid to dark navy wool suit with structured shoulders and trousers tailored to a slight break. A white shirt and a burgundy grenadine or subtly patterned tie add texture; grenadine has a woven surface that photographs with more depth than flat silk. Dark brown oxfords make it friendlier for daytime than black. Add a white pocket square, burgundy boutonniere and a plain watch. A matching waistcoat on the groom only is a simple way to set him apart.
9. Olive Green Suit Groom Attire
Olive is the relaxed cousin of forest green, so it suits outdoor and garden ceremonies with a dressy-casual dress code. Keep it muted; saturated olive can turn khaki-army in daylight. Pair it with a white, cream or pale blue shirt and a chocolate, rust or dark green tie. Medium-brown derbies or brogues work naturally with the earthy suit. A matching belt, cream pocket square and greenery boutonniere finish it. If the evening forecast is cold, a brown wool overcoat over olive looks far better than a black coat. I wouldn't use olive at a formal evening wedding.
10. Velvet Dinner Jacket Groom Attire
A velvet dinner jacket is a statement, so it needs a formal setting to look intentional. Burgundy, emerald, navy or black velvet with satin shawl or peak lapels pairs with black tuxedo trousers, a white formal shirt and a black silk bow tie. Black velvet slippers or patent oxfords complete it. The boutonniere should match the jacket color rather than fight it, and the pocket square should stay white. Velvet crushes where you sit and lean, so hang it on a wide-shouldered hanger and steam it lightly from inside on the morning. Skip patterns entirely; the texture is the detail.
11. Gray Herringbone Suit Groom Attire
Herringbone gives gray tailoring a texture you notice up close without it dominating the photos from across the room. Medium or charcoal gray wool with a fine weave is the version I'd pick, since a large herringbone can shimmer on camera. A white shirt and a dark green, burgundy or navy tie add the season. A matching waistcoat makes it more formal and warmer outdoors. Dark brown brogues suit a country setting, black oxfords an indoor venue. A patterned pocket square, tie bar and dress watch finish it. Gray herringbone fits nearly any wedding color scheme, which makes it the safe choice for a groom who wants texture but not a bold color.
12. Double-Breasted Suit Groom Attire
Double-breasted jackets give the groom a stronger silhouette and set him apart from a row of single-breasted groomsmen at a glance. For October, I'd choose charcoal, navy, dark brown or forest green wool with a six-button front and peak lapels. A white spread-collar shirt and a solid or textured tie in a fall shade suit the wider lapel. Black or dark brown oxfords and matching socks keep the trouser line clean. Pin the boutonniere higher on the wider lapel so it doesn't drift toward the shoulder. This jacket must stay buttoned when standing, so it has to fit comfortably closed; an open double-breasted jacket flaps like a curtain.
13. Tan Suit Groom Attire
Plenty of places are still warm in October, and for those weddings a tan suit is more comfortable and more appropriate than dark wool. Choose a medium-weight wool, cotton-wool or breathable blend in camel, taupe or warm beige. A white shirt with a dark brown, burgundy or forest green tie pulls the light suit toward autumn. Brown loafers, derbies or brogues finish it depending on formality. Lighter cloth shows creases and sweat more readily, so I'd steer a groom who runs warm toward wool rather than pure cotton. Put him in a three-piece and the groomsmen in two-piece versions for an easy distinction.
14. Black Suit With Rust Tie Groom Attire
A black suit turns surprisingly autumnal with one warm accent. Start with a well-tailored black wool suit and a crisp white shirt, then add a textured rust, copper or burnt orange tie. Black cap-toe oxfords and a black belt keep the base formal. A cream pocket square softens the contrast more gently than white, and a boutonniere of rust flowers and greenery repeats the tie color. A black waistcoat adds presence if the groomsmen are in plain two-piece suits. Stop at one orange element; a rust tie, rust square and rust socks together look themed. It suits evening and industrial venues.
15. Plaid Suit Groom Attire
Plaid is for the groom who wants personality, but scale is everything. A restrained windowpane or Prince of Wales check on dark navy, gray, brown or green reads as texture from a distance, while a bold check dominates every group photo. Keep the shirt solid white or pale blue and the tie plain burgundy, navy or green so there's only one pattern. Dark brown brogues, a matching belt, solid socks and a simple pocket square finish it, with a compact boutonniere. A good tailor will also match the check across the seams and pockets, which is the sign of a well-made patterned suit. Groomsmen in solid suits from the same color family keep it calm.
Rental, Off the Rack or Made to Measure
How the groom gets his suit changes the timeline. Rentals are measured in advance and usually arrive the week of the wedding, which leaves little time to fix a poor fit. Off-the-rack suits need alterations, and a busy tailor in wedding season can need a few weeks. Made-to-measure takes longest of all, so order it several months ahead.
What I Check at the Last Fitting
- The jacket collar sits flat against the shirt collar when he stands naturally.
- Roughly a quarter to half an inch of shirt cuff shows below the jacket sleeve.
- The jacket button closes without pulling into an X across the stomach.
- Trousers touch the shoe with a slight break, or none for a slimmer cut, and don't pool.
- He can sit, raise his arms and hug without the shoulders riding up toward his ears.
Bring the wedding shoes and the actual shirt to that fitting. Trouser length is set against the shoe heel, and a different shirt collar can change how the jacket sits at the neck. Polish or break in the shoes at least a week before, because stiff new leather on a long wedding day is how grooms end up limping by the first dance.
Dressing the Groom for Every Hour of the Day
Every groom outfit here comes back to the same decisions: the dress code, the venue, the weather and what the man actually likes wearing. Black and midnight navy tuxedos belong at formal evenings; charcoal, brown, green and burgundy suits bring color to daytime and cocktail celebrations. Tweed and herringbone suit rustic settings, and velvet or double-breasted tailoring makes a stronger statement. Spend money on alterations and shoes he can stand in for hours before any accessory. Then give the groom one or two details his groomsmen don't have, such as a waistcoat, a special tie or a different jacket, and he'll look like the groom in every photo.
