17 Groomsmen Outfit Ideas for Plus Size Men You Need to Try

Finding a suit that fits well is hard enough. Finding one that fits well, feels good for eight hours, and still looks sharp in every photo is where plus size groomsmen often get stuck.

Rental racks run small, the wrong cut pulls across the middle, and a lot of advice online amounts to just wear black. This list is here to change that.

These groomsmen outfit ideas for plus size men come from real weddings and real guys, not studio mockups.

You’ll see charcoal suits with open collars, double breasted jackets that sit flat, cream and white tuxedos with wide lapels, pinstripes that actually work, and a whole red group on a staircase.

Each look shows what to copy, from jacket buttons to trouser breaks to shoe choices.

Look for the small things that repeat. A jacket that closes without pulling. Trousers that hang straight. One warm accent like brown shoes or a gold pin.

Whether the wedding is a garden brunch or a black tie evening, there’s a look below that fits the setting and your frame.

1. The Charcoal Suit With an Open Collar and Brown Shoes

A single-breasted charcoal suit, a white shirt with no tie, and tan leather shoes. That’s the whole outfit, and it works.

What makes it work here:

• The jacket skims the body instead of pulling across the middle, so the shoulders stay clean and the front hangs straight.
• Matching jacket and trousers in one solid color make an unbroken vertical line from collar to shoe.
• The open collar keeps the neck area relaxed, which matters if a tight top button bothers you by hour three.
• Brown shoes warm up the cool grey and keep it from looking like office wear.

2. The White Dinner Jacket With Black Satin Lapels

White jackets get skipped a lot by bigger guys, and this one is a good reason to reconsider. The black satin lapels do the heavy lifting.

They’re wide and angled, so they draw a sharp V down the center of the chest and pull the eye up and in.

Everything below the jacket is black. Black trousers and glossy black lace-ups make one long dark column, so the white stays up top where the bow tie and shirt studs finish it off.

The jacket closes on a single button, and the pocket flaps carry a thin black trim that echoes the lapels.

One warning for the groomsmen group: white shows every crease. Steam it the morning of the wedding, not the night before.

3. The Brown Double Breasted Suit With Sneakers

Chocolate brown is a warmer, less expected pick than navy or grey, and it photographs well in daylight. Here it’s paired with a white shirt, an open collar, and a patterned pocket square that picks up the same dark tones.

What works here:

• The double breasted front has gold tone buttons, which give the jacket some character without needing a loud tie or vest.
• The jacket has room through the body, so the buttons sit flat instead of pulling.
• One shade from jacket to trousers keeps the outfit simple and the line unbroken.
• The trousers are cropped with a small cuff, and the chunky sneakers in grey, white, and brown echo the suit color.

4. The Black Three Piece Tuxedo With a White Rose Boutonniere

Formal doesn’t get more classic than this, and the details are what keep it from looking like a rental. A black tuxedo jacket with satin shawl style lapels, a matching low cut vest underneath, a black bow tie, and a crisp white shirt.

A single white rose with a green stem sits on the lapel, and a flat white pocket square sits just above it.

The vest is the quiet hero. It sits smooth over the midsection and covers the shirt front, so the waist area stays one clean block of black instead of a break between shirt and trousers.

The jacket drapes loose through the body and the sleeves have room around the arm, so nothing pulls when he moves.

5. The Navy Three Piece With Pinstripe Trousers and a Brown Fedora

Pinstripes on a bigger frame can go wrong fast, but here the pattern stays in one place.

The jacket and vest are solid navy, and only the trousers carry the thin vertical stripes. Those lines run straight down the leg, so they read as length and not as busyness.

The vest does a lot of work. Its buttons have a warm reddish brown tone, and that same color shows up again in the belt, the shoes, and the brown felt fedora.

A pale floral tie in soft blues and greens adds a light patch in the middle, and a white pocket square repeats it near the shoulder. Tortoiseshell glasses finish the group.

6. The All Black Suit With a Matching Black Shirt

No tie, no vest, no color. A black suit worn over a black shirt with the collar open at the neck. The look is quiet and a little moody, and it suits an evening wedding in a venue with warm lighting and white flowers like the one behind him.

Because the shirt and jacket are the same shade, there’s no break at the chest. The eye reads one tall dark shape, and that’s what makes it slimming.

The jacket fits through the shoulders and chest, and the trousers fall straight to the shoe with a clean line and no pooling at the hem. Black leather lace-ups with a soft shine finish it.

The one watch on his wrist is the only accessory, and it’s enough. Adding more would crowd a look that depends on being simple.

7. The Light Grey Suit With a Dark Crew Neck Tee and a Black Wide Brim Hat

Light grey in sunlight looks fresh and easy, and here the suit gets a casual twist. Instead of a dress shirt, he wears a dark navy crew neck tee under the jacket. No collar, no tie, nothing to button at the neck.

The jacket has a soft woven texture that catches the light and keeps the grey from looking flat. It’s cut with enough room across the chest and arms, so the sleeves hang without tightness.

The dark tee makes a long, narrow strip down the center, and that strip does the same job a tie would, only quieter.

The black wide brim hat ties the dark tee to the top of the look. A plain ring on his finger is the only other detail.

Ways to copy this:

1. Choose a tee in a thick, smooth fabric. Thin cotton clings and wrinkles.
2. Pick a dark color, navy or black, so the contrast with the grey stays strong.
3. Let the tee hem sit under the jacket, not hanging out below it.

8. The Black Double Breasted Suit With a Slim Black Tie

Double breasted jackets have a reputation for adding bulk, but this one shows the other side. The peak lapels are wide and sharp, and they point up toward the shoulders, which opens the chest and keeps the front from looking like a wall of fabric.

Six buttons sit in two tidy columns, and the jacket closes smoothly without any strain or wrinkles around the middle.

The shirt is crisp white, the tie is slim black, and a dark folded pocket square sits flat in the chest pocket. A small lapel pin adds a tiny detail near the collar.

Since the trousers match the jacket and fall straight to the floor, the whole body reads as one clean column.

The tie is where many guys go wrong with this style. Keep it narrow and plain. A wide, shiny one would fight the lapels.

9. Two Groomsmen, Two Shirts, One Dark Jacket Color

This one shows how a group can match without matching exactly. Both men wear dark jackets in nearly the same deep shade, but the shirts under them go in different directions.

On the left, a white shirt with dark buttons and a soft woven texture. On the right, a navy shirt covered in a light blue paisley print with a button down collar.

The paisley guy is the useful example for anyone nervous about pattern. The print is small and the colors stay within blue and white, so it reads as one soft texture and not a loud statement. His jacket is left open, which keeps the front relaxed.

The white shirt guy shows the other side. His jacket hangs open too, and the shirt has room across the front, so the buttons lie flat without gaping. When the shirt fits, an open jacket looks intentional.

10. Two Black Tuxedos With Bow Ties and Sunglasses at a Daytime Reception

Bright afternoon sun and black tuxedos can work together, and this pair proves it. Both men wear black jackets with satin lapels, crisp white shirts, and black bow ties.

The shirt on the left has small black studs down the front, and the jacket on the right closes on a single button.

What keeps them from looking stiff is the small stuff. Dark aviator style sunglasses cut the glare and add attitude.

A gold watch on one wrist and a small gold lapel pin on the other jacket bring in a little warmth. Both jackets have broad shoulders and room through the arms, so there’s no pulling when they hold a drink.

The trousers are straight and full enough to hang cleanly, ending right at the glossy black shoes.

The cuffs are worth a note. The shirt cuffs peek out just past the jacket sleeves, a small detail that makes the outfit look finished.

11. The Groom in White Beaded Lapels, Surrounded by Groomsmen in Deep Red

Seven men in matching deep red double breasted suits, and one in white at the front. Nobody has to guess who the groom is. The group is a good model for how to stand one man out without changing the whole outfit plan.

The groom’s jacket is white with beaded and embellished peak lapels and matching detail on the cuffs.

Under it, a white shirt with black studs, a black bow tie, and black trousers. The details sit high on the chest and at the wrists, right where cameras land.

The groomsmen stay simple. Gold toned buttons on the red jackets, black ties, white shirts, and a small yellow gold pocket square folded flat.

Several wear dark sunglasses, which gives the group a sharp, unified look on the stairs.

12. The One Button Black Tuxedo With Peak Lapels and a Steel Watch

A mirror selfie before leaving the house, and it’s a useful one. The jacket is black with sharp peak lapels in a matte finish, closed on a single button.

Under it, a white shirt with a hidden placket, so no buttons break up the front, and a plain black bow tie at the collar.

The single button matters. It makes one low closing point, which lets the lapels fall in a long straight line from shoulder to waist.

The jacket also hangs loose and straight, with side pockets that lie flat and no pulling at the front.

The watch is the one shiny thing in the outfit. A steel bracelet watch with a dark face catches the light against the black sleeve and the white cuff, and nothing else competes with it.

Before you leave the house:

1. Do a mirror check from the front and the side.
2. Button the jacket once, then sit down and stand up again to see how it settles.
3. Make sure a bit of white cuff shows at each wrist.
4. Straighten the bow tie last.

13. The Ivory Double Breasted Dinner Jacket in a Garden Setting

Soft white against olive trees, lavender, and white brick looks like it was planned, and for a garden wedding it nearly is.

The jacket is a creamy ivory with wide peak lapels, closed on a double breasted front with pale buttons that blend into the fabric. Nothing shiny interrupts the color.

Black trousers and glossy black lace-ups ground it. A white shirt and a small black bow tie sit at the neck, and dark sunglasses add a laid back finish for the afternoon light.

The shape is worth studying. The jacket ends at the hip and has plenty of room through the shoulders and arms, so the sleeves hang straight and the front closes flat.

The long peak lapels angle outward and make the chest look open, not crowded. Light on top and dark below also splits the body into two clear blocks, which keeps the outfit looking tidy from head to toe.

14. The Navy Pinstripe Three Piece With a Gold Tie and Pocket Watch Chain

Tone on tone stripes are the trick here. The jacket, vest, and trousers are all cut from the same navy pinstripe, so the pattern repeats evenly and never fights itself.

From a few steps away the lines read as soft texture, and up close they give the outfit a vintage, old money feel that suits a estate or garden venue.

A matching vest sits smooth under the jacket and ends right at the trouser waist, so the middle of the body is covered by one clean layer.

A muted gold tie in a flat satin finish stands out against all that navy, and a thin gold chain loops across the vest toward a small pocket watch. A flat white pocket square keeps the chest simple.

Dark brown cap toe oxfords finish it. They’re a warmer choice than black and they pick up the gold in the tie and chain.

15. The Navy Double Breasted Suit With a Light Blue Shirt and a Burgundy Tie

A candid photo from a real garden reception, and it shows what a guest at ease looks like.

The navy jacket is double breasted with four buttons set in a square, wide peak lapels, and a flap chest pocket with no pocket square. Under it, a pale blue shirt and a burgundy tie with a tiny repeating pattern.

The light shirt does the work here. Pale blue sits between the dark jacket and his face, so the neck area looks open and the navy doesn’t swallow him up.

The burgundy tie adds one warm note, and because the pattern is so small it reads as a solid from a few feet away.

The jacket is cut with room, so the front sits flat and the sleeves hang straight, even while he holds a phone in one hand. A bit of shirt cuff shows at the wrist. The trousers match and fall straight, with nothing to adjust.

Navy is the safest base color for a whole group. Let the tie be where each man gets a little personal choice.

16. The Dark Taupe Double Breasted Suit With a Black Tie

Warm grey with a hint of brown is an easy color to overlook, and it deserves a second look.

This suit sits between charcoal and chocolate. It’s softer than black and less stark than navy, so it suits a groomsman who wants a formal look that doesn’t feel like a uniform.

The double breasted jacket has wide peak lapels and black buttons set in a clear grid. That dark hardware stands out against the lighter cloth, which gives the front some structure without any extra layers.

He’s fastening the jacket as he stands, and it closes flat across the front, with room left in the shoulders and sleeves.

Under it, a white shirt and a slim black tie draw a sharp vertical line down the center. A steel watch and a thin silver bracelet are the only shine.

The trousers have a straight leg with a clean front crease, so the line from jacket hem to floor stays unbroken.

17. The Cream Tuxedo Jacket With Black Peak Lapels and a Pleated Shirt Front

Cream and black is a pairing that never needs explaining. This jacket is a warm off white with wide black satin peak lapels that sweep from the collar down to a single button at the waist.

The lapel is the star, and its size keeps it in proportion with a broader chest and shoulders.

Look closer and the small details do the finishing. Narrow black trim lines the pocket openings, matching the lapels.

The shirt has a pleated front with black studs, and a black bow tie sits at the collar. Black trousers with a clean crease fall straight from under the jacket.

Compare this with the white dinner jacket earlier in the list. That one had wide lapels and a bold, high contrast front.

This cream version feels softer, since the off white warms up in daylight and looks less stark next to green lawns and blue sky.

A good sign of fit here: the jacket hangs straight from the shoulders and closes without a pull line. The single button does the closing, so the fabric never has to stretch across several points.
