September is an awkward month for wedding menswear. The suits have to look like fall in the photos, but the men inside them may be standing in late-summer sun. I plan these outfits from the dress code, ceremony time, venue, forecast and the wedding palette, roughly in that order. Lightweight wool and breathable wool blends almost always beat heavy winter cloth this month, and navy, brown, olive, burgundy and charcoal carry the season through color. The groom also needs one clear difference from his groomsmen, whether a different jacket, a vest, a richer tie, a lapel style or a bigger boutonniere, so the group reads as a team with an obvious lead. The fifteen combinations below cover ballrooms, barns, gardens, beaches, vineyards and modern venues.
Renting or Buying Suits for the Groomsmen
Before picking a color, decide whether the party is renting or buying. It changes which looks on this list are realistic.
- Renting suits tuxedos, black and midnight blue formalwear, and parties where groomsmen are spread across the country. Rental shops measure locally and ship matching pieces, so the colors are consistent.
- Buying makes sense for navy, charcoal and gray, which a groomsman will wear again to work or other weddings. A bought suit can also be tailored properly, which rentals allow only in a limited way.
- Statement colors such as burgundy, forest green, tweed or plaid are usually bought, and usually only for the groom.
- Costs vary widely by region and shop, so get quotes for the whole party before committing the groomsmen to a purchase.
A mixed approach is common: the groom buys his suit and keeps it, while the groomsmen rent or buy a matching navy or charcoal and wear their own shoes in an agreed color.
1. Navy Suits With Burgundy Ties
Navy with burgundy is the combination I'd hand a groom who wants something safe that still says autumn. Groomsmen go in matching two-piece navy suits, white shirts, burgundy ties, brown leather Oxfords and plain white pocket squares. The groom wears the same navy as a three-piece, with a subtly patterned burgundy tie and a fuller boutonniere. Get a lightweight wool if the ceremony is in the afternoon; a navy jacket in full sun gets hot quickly, and dark cloth shows sweat less than light. Dark brown shoes add depth without weight. Navy also sits comfortably next to blush, rust, plum or champagne bridesmaid dresses.
2. Charcoal Suits With Rust Ties
Charcoal is quieter than navy and lets a rust tie do more. Put the groomsmen in single-breasted charcoal suits, white shirts, rust ties, dark brown shoes and belts to match. The groom gets a three-piece with a textured vest, a patterned rust tie and a cream pocket square. For early September I'd choose a smooth, open-weave worsted; a lightly textured wool makes sense for a cooler late-month date. Socks should match the trousers, or quietly pick up the rust if the group is relaxed. Keep the metal to tie bars and watches. It suits city, industrial and dressier outdoor settings.
3. Olive Green Suits With Black Ties
Olive is the most natural green for a wedding suit, provided you keep it muted. A bright or yellowish green tips into costume fast. Groomsmen wear olive suits with white shirts, slim black ties, black loafers or Oxfords and white pocket squares. The groom stands out with a deeper forest-green vest under his olive jacket, or switches to a black bow tie. Black accessories keep olive sharp; brown would soften it into a casual look. Olive does shift color under different light, so view the fabric outdoors before ordering for the whole party. Dark socks and small greenery boutonnieres finish it.
4. Tan Suits With Terracotta Ties
Tan suits are made for a warm September afternoon outdoors, especially in golden late-day light. Groomsmen wear lightweight tan with ivory or white shirts, terracotta ties, medium-brown loafers and cream pocket squares. The groom goes a shade darker in camel, or adds a tan vest and a patterned terracotta tie. Avoid very pale tan for a formal wedding; it looks flimsy in photos, and a richer shade holds up better. Tan wrinkles more than darker wool, so steam the suits on the morning and don't let anyone sit in the car in the jacket. Match belts closely to the shoes.
5. Chocolate Brown Groom With Navy Groomsmen
Putting the groom in chocolate brown and the groomsmen in navy gives you an instant focal point. The groom wears a rich brown three-piece with a white shirt, champagne tie, dark brown Oxfords and an ivory pocket square. Groomsmen wear navy two-pieces with white shirts, brown ties, brown shoes and champagne pocket squares, so brown and champagne travel through the whole group. The detail that matters is fabric weight. If the brown suit is a heavy flannel and the navy is a summer worsted, the groom looks dressed for a different month. Order both in similar cloth weights and finishes.
6. Burgundy Groom With Charcoal Groomsmen
Burgundy is a bold suit color, so I keep it for the groom only and ground everyone else in charcoal. His outfit is a tailored burgundy suit, white shirt, black tie, black shoes and a white pocket square. Groomsmen wear charcoal with white shirts, burgundy ties, black Oxfords and restrained burgundy pocket squares. Choose a matte burgundy cloth; anything with a sheen looks like a stage costume under flash. It plays best at evening ceremonies and indoor venues with warm light. Give the groom the fuller boutonniere and the groomsmen smaller matching ones.
7. Forest Green Groom With Tan Groomsmen
A forest-green groom framed by tan groomsmen is one of the more distinctive pairings here, and it works because both colors come from the same outdoor palette. The groom wears a forest-green three-piece, ivory shirt, brown tie and dark brown shoes. Groomsmen wear tan suits with ivory shirts, forest-green ties and brown loafers. Keep the shirt color identical across everyone; it's the thread that connects two very different suit colors. The tan needs some depth, or it reads like a summer office suit. Greenery boutonnieres with small cream flowers suit it.
8. Black Tuxedos With Ivory Accessories
For a formal September evening, black tuxedos remain the cleanest answer. Groomsmen wear black shawl or peak-lapel tuxedos, white tuxedo shirts, black bow ties, patent or highly polished shoes and ivory pocket squares. The groom can switch to an ivory dinner jacket with black trousers, or stay in black and add a waistcoat and fuller boutonniere. Cover the waistband with a cummerbund or vest; a visible shirt bunching above tuxedo trousers is the classic black-tie mistake. Early September evenings can still be warm, so choose a lightweight tuxedo cloth and leave velvet jackets for winter.
9. Midnight Blue Tuxedos With Black Bow Ties
Midnight blue is a black-tie color that actually looks richer than black under artificial light, where black can go flat. Groomsmen wear midnight blue tuxedos with black satin lapels, pleated or bib-front white shirts, black bow ties, patent shoes and white pocket squares. The groom can differ by wearing a three-piece or by taking peak lapels while the others wear notch or shawl. Socks must be black and long enough that no leg shows when seated. Studs and cuff links complete the shirts. Leave out brown shoes, colored belts and anything casual; formal wear only works when every piece follows the rules.
10. Brown Tweed Suits With Cream Shirts
Tweed is for a genuinely cool September, a mountain venue or a late-month country wedding. On a hot afternoon it's miserable. Groomsmen wear brown herringbone suits, cream shirts, burgundy ties, dark brown brogues and neutral pocket squares. The groom gets a three-piece with a coordinating waistcoat and a patterned burgundy or forest-green tie. Polished, slim leather boots can replace brogues at a farm or lodge. Tweed already carries a lot of texture, so keep pocket squares plain and ties smooth. Dark socks and small seasonal boutonnieres finish it.
11. Light Gray Suits With Sage Ties
Light gray with sage is my pick for a September wedding that still feels like summer. Groomsmen wear lightweight gray suits, white shirts, muted sage ties, medium-brown loafers and white pocket squares; the groom wears a slightly darker gray three-piece with a patterned sage tie. Go for a medium-light gray rather than silver, which looks shiny and dated in photos. Brown shoes warm up the cool gray. Light suits show sweat at the back and underarms more readily than dark ones, so a breathable shirt fabric and a cool spot for the groomsmen before the ceremony help a lot.
12. Beige Suits With Chocolate Brown Accessories
Beige only looks sophisticated when every accessory is deliberate, because a pale suit shows any lazy choice. Groomsmen wear beige two-pieces, crisp white shirts, chocolate ties, brown loafers and cream pocket squares; the groom adds a matching vest, a dark brown knit or patterned tie and a richer boutonniere. Wool-linen or a breathable wool blend holds its shape far better than pure linen, which creases within an hour. No-show socks with loafers can pass at a very relaxed beach ceremony, but regular dress socks are the safer choice for anything semi-formal.
13. Plaid Groom Suit With Solid Groomsmen Suits
A plaid groom suit beside solid groomsmen is a nice way to give the groom character without a color clash. He wears a subtle brown-and-navy plaid three-piece, white shirt, solid navy tie, brown brogues and cream pocket square. Groomsmen wear solid navy with white shirts, brown ties and brown shoes, repeating his colors. The plaid has to be low contrast and small in scale; big checks look loud in photos. On a good suit the pattern lines up at the seams, especially at the chest pocket and across the back, so check that before buying. Keep his boutonniere small.
14. Black Suits With Champagne Ties
Black suits with champagne ties sit between formal and semi-formal, which makes them easy to adapt to the venue. Groomsmen wear tailored black suits, white shirts, champagne ties, black Oxfords and ivory pocket squares; the groom wears a black three-piece with a patterned champagne tie, dress watch and a larger boutonniere. Choose matte ties, since shiny champagne satin looks cheap under flash. Black socks and belts keep the line unbroken down to the shoe. If the palette includes gold, bring it in only through cuff links or tie bars.
15. Earth Tone Groom And Groomsmen Suits
Mixing earth tones across the party lets each man look a little different while the group still reads as one palette. The groom wears a dark olive three-piece, ivory shirt, rust tie and brown Oxfords. Groomsmen alternate muted brown and taupe suits, all with ivory shirts, olive ties, rust pocket squares and brown shoes. The rules that hold it together: similar cloth weight, similar lapel width, same level of formality, and no more than three main colors. I'd see every suit together before alterations begin, because a mismatch is cheap to fix then and impossible on the day. Keep boutonnieres, belts, socks and shoes consistent.
Fitting Groomsmen Who Live Far Apart
A wedding party rarely lives in one town. The way to keep the fit consistent is to standardize the measurements, not just the suit.
- Have each groomsman measured by a tailor or rental shop, never at home with a tape. Home measurements are where most fit problems start.
- Get every suit delivered at least three to four weeks before the wedding, so there is time for alterations if something is off.
- Agree on one trouser break for everyone, a slight break or none. A row of men with different trouser lengths shows instantly in group photos.
- Ask each man to try on the full outfit, shoes included, and send a photo standing straight and one with arms raised.
Fit Details the Camera Picks Up
Group photos put every suit side by side, so small differences jump out. The shirt cuff should show about a quarter to half an inch below the jacket sleeve on everyone. Jackets should close without pulling into an X at the button. Collars should sit against the neck, without a gap at the back. Ties should all end around the belt line. Fix these during fittings, and the photographs will look like a tailored group rather than six separate suits.
Getting the Whole Party Dressed for a Warm Fall Wedding
Good September menswear comes down to seasonal color in a cloth light enough for the actual weather. Start from the venue and dress code, then decide whether the day leans toward late summer or early fall. Any of the colors above work once the fabric and accessories match the setting. Keep the groomsmen consistent and give the groom one or two clear differences, such as a vest, a different jacket, a richer tie, a pattern or a bigger boutonniere. Then book alterations early and agree on footwear for everyone. That's what makes the group photos look right.
