Weddings are full of beautiful details, and the boutonniere is one of the most personal. It sits right over the heart, small but powerful. But if you’ve ever been handed a pin and told to just attach it, you know how stressful that moment can be. How to pin a boutonniere the right way is not something most people are taught growing up, yet it’s expected at almost every formal event.
The good news? It’s actually pretty simple once you know what you’re doing. Learning how to pin a boutonniere correctly takes less than two minutes, and the results make a huge difference. A crooked flower or a torn lapel can distract from an otherwise perfect look. A well-pinned boutonniere, on the other hand, looks effortless and polished all day long.
In this guide, we’re going to walk you through everything from the supplies you need to the exact pinning technique, to the most common mistakes people make and how to avoid them. Whether you’re a best man, a mother of the groom, or the person in charge of getting everyone ready on wedding day, knowing how to pin a boutonniere is a skill you’ll use again and again.
What Is a Boutonniere and Why Does It Matter?
A boutonniere (pronounced boo-tuh-NEER) is a small floral arrangement worn on the left lapel of a suit or jacket. The word comes from French, meaning “buttonhole.” Historically, it was placed through a real buttonhole on the lapel. Today, most suits don’t have working buttonholes, so we use pins instead.
Boutonnieres are worn at:
- Weddings (grooms, groomsmen, fathers, ring bearers)
- Proms and homecoming events
- Military balls and formal galas
- Funerals and memorial services
- Graduation ceremonies
The boutonniere is a symbol of elegance and care. When it’s pinned beautifully, it says attention was paid to the details. When it’s flopping sideways or stabbing someone in the chest, it says the opposite.
Supplies You Need Before You Pin
Before you learn how to pin a boutonniere, make sure you have everything ready. Rushing through this with the wrong tools causes most of the common mistakes.
| Supply | Why You Need It |
| Boutonniere pin (2–3 inches long) | Long enough to go through the stem and fabric safely |
| The boutonniere itself | Fresh, with stem trimmed and wired if needed |
| A jacket or suit with a left lapel | This is where it goes always the left side |
| A mirror or second person | Helps with placement and symmetry |
| Optional: Floral tape | Can reinforce the stem for a cleaner finish |
| Optional: Magnet boutonniere holder | A no-pin alternative for delicate fabrics |
Always use boutonniere pins, not regular straight pins. Boutonniere pins are pearl-headed and longer. They go through fabric more cleanly and look much more elegant.
Where Exactly Does a Boutonniere Go?
This is one of the most searched questions around how to pin a boutonniere, and it’s a fair one. Placement matters.
- Location: Left lapel of the jacket, always
- Height: About 4 inches below the left shoulder seam
- Position: Just above or at the lapel’s buttonhole (if there is one)
- Angle: The flower should face outward and slightly upward
If the person crosses their heart with their right hand, the boutonniere sits right under that hand. It should sit flat against the lapel, not sticking out like a spike.
How to Pin a Boutonniere: Step-by-Step
Here is the complete, easy-to-follow method for how to pin a boutonniere without damaging the fabric or hurting anyone.
Step 1: Prepare the Boutonniere
Before you touch the suit, hold the boutonniere and check it:
- Make sure the stem is trimmed (about 1–2 inches of stem below the flower)
- If the florist wired the stem, it should feel firm and bendable
- Remove any wilted petals or loose leaves
- Keep it upright so the petals don’t get crushed
Step 2: Hold the Boutonniere in Place
- Stand in front of the person who will wear it
- Hold the boutonniere against their left lapel with your non-dominant hand
- The flower head should be near the top of the lapel
- The stem should point downward at a slight angle (like 5 o’clock on a clock face)
- Make sure it sits flat, not poking outward
Step 3: Take the Boutonniere Pin
- Hold the boutonniere pin in your dominant hand
- Pearl or decorative head should be on the outside (visible side)
- The sharp tip should point toward the lapel
Step 4: Insert the Pin Through the Stem
This is the most important part of learning how to pin a boutonniere:
- Push the sharp tip of the pin into the stem from the front
- Go through the stem completely
- Then push the pin into the back of the lapel fabric
- Push it back out through the front of the lapel fabric (just a small scoop of fabric about ¼ inch)
- Finally, guide the pin tip back into the stem from the other side
This “in-out-in” motion through the stem anchors the flower to the fabric securely.
Step 5: Check That the Pin Is Hidden
The pin should be mostly hidden behind the stem. You should only see the pearl head on top. If the pin is showing too much, adjust the angle slightly.
Step 6: Check the Angle and Position
Step back and look. The boutonniere should:
- Sit flat against the lapel
- Face forward (flower petals toward the viewer)
- Be level or very slightly angled
- Not poke the wearer when they move
Step 7: Optional Second Pin for Security
For long events like weddings, many professionals use two pins, one near the top of the stem and one near the bottom. This keeps the boutonniere from spinning or drooping during a long day.

| 4 | Insert through stem, scoop lapel fabric, back into stem | Never go straight through fabric only |
| 5 | Hide the pin behind the stem | Only pearl head should be visible |
| 6 | Check angle and position | Flat, forward-facing, level |
| 7 | Add second pin if needed | Prevents drooping at long events |
How to Pin a Boutonniere on Different Fabric Types
Not all suits are the same, and knowing how to pin a boutonniere on different fabrics is key to avoiding damage.
On Wool or Thick Fabric Suits
This is the easiest. Wool holds the pin well. Use standard pinning technique with no worries.
On Silk or Satin Lapels
Be very careful. Silk is delicate and can show pinhole damage.
- Use the smallest scoop of fabric possible
- Consider a magnet boutonniere clip as an alternative
- Use two pins for balance instead of one large one
On Velvet Suits
Velvet shows pressure marks easily. Pin through the least visible area and use minimal fabric in your scoop.
On Linen Suits
Linen is a bit looser in weave. You may need a slightly larger fabric scoop to prevent the pin from slipping.
On Tuxedos with Satin Lapels
Same as silk, be extra gentle. Many formal tuxedos actually have a proper buttonhole on the left lapel. If so, slide the stem through the buttonhole and use just one pin at the back for support.
How to Pin a Boutonniere Without Damaging the Suit
This is one of the biggest worries people have when they’re figuring out how to pin a boutonniere. Nobody wants to ruin a rental tuxedo or an expensive suit.
Follow these rules to protect the fabric:
- Never push the pin straight through the lapel: From front to back. This leaves a visible hole.
- Always scoop: Go into the fabric at an angle and come back out the same side.
- Use the stem as your anchor:Â The pin goes through the stem, not just the fabric.
- Don’t force a dull pin: If your pin is bending or you’re pressing hard, get a sharper one.
- Keep your scoop small: ¼ inch of fabric is enough. More than that creates a bigger hole and can pucker the lapel.
Common Mistakes When Pinning a Boutonniere
Even when people know how to pin a boutonniere, these mistakes still happen all the time.
Mistake 1: Pinning Too High or Too Low
Too high, and the boutonniere competes with the collar and tie. Too low, and it gets lost on the jacket body. The sweet spot is about 4 inches below the shoulder.
Mistake 2: The Flower Faces the Wrong Direction
The flower should face the viewer, not point up toward the ceiling or down toward the floor. Always check from the front.
Mistake 3: Going Straight Through the Fabric
This is the #1 fabric-damaging mistake. Always scoop the fabric in one side, out the other.
Mistake 4: Forgetting the Stem
Some people try to pin just the flower head, skipping the stem anchor. The stem is what holds everything together. Always pin through the stem.
Mistake 5: Using One Pin for a Long Event
One pin works fine for quick photos. For a full wedding day, always use two pins to prevent drooping.
Mistake 6: Pinning on the Right Side
Boutonnieres always go on the LEFT lapel. Always. It’s tradition, and it’s the rule.
How to Pin a Boutonniere: Tips for the Wedding Day
Wedding days are busy and often rushed. Here are expert-level tips for how to pin a boutonniere efficiently when you’re doing it for multiple people.
- Assign one person to pin all boutonnieres. Consistency matters.
- Do it before photos, but after everyone is dressed and ready.
- Have extra pins on hand; they get dropped and lost constantly.
- Keep boutonnieres in water until the last possible moment to keep them fresh.
- Pin groomsmen in order (groom first, then best man, then groomsmen) so you can check for consistency.
- Take a photo reference of a perfectly-pinned boutonniere so each one matches.
Boutonniere Styles and How They Affect Pinning
Knowing how to pin a boutonniere also means understanding that different styles require slightly different handling.
| Boutonniere Style | Pinning Notes |
| Single rose | Classic and easy pin through the thick stem |
| Succulent boutonniere | Heavier than flowers; use two pins always |
| Wildflower boutonniere | Stems may be thinner; use gentle pressure |
| Corsage-style boutonniere | Usually has a built-in pin or magnet check with florist |
| Greenery-only boutonniere | Use fine stems carefully; may need floral wire wrap |
| Feather boutonniere | Pin through the quill end; avoid crushing feathers |
Alternatives to Traditional Pinning
If you’re nervous about how to pin a boutonniere the traditional way, these alternatives work beautifully:
Magnetic Boutonniere Holders
These use two magnets, one on the front (holding the boutonniere) and one on the inside of the lapel. No pinhole at all. Great for delicate fabrics or anyone who gets anxious about pins.
Boutonniere Clips
Similar to lapel pin clips, slide them onto the lapel edge. The stem sits in a small vase-style holder.
Existing Buttonhole
If the suit has a working lapel buttonhole, slide the stem through it. This is the original and most classic method. Use a single pin at the back just to keep it from spinning.
How to Keep a Boutonniere Fresh All Day
Knowing how to pin a boutonniere perfectly is only half the battle; you also need it to last through the ceremony, dinner, and dancing.
- Keep it refrigerated until about 30 minutes before wearing
- Don’t mist it with water after pinning, as this can cause petals to spot
- Avoid direct sunlight and heat
- Have the florist condition the stems with floral preservative
- Use flowers known for longevity: roses, orchids, succulents, and carnations last longest
- Avoid flowers that wilt quickly: gardenias, lilies of the valley, and sweet peas

How to Pin a Boutonniere FAQs
1. Which side does a boutonniere go on?
Always the left side. This is standard for all formal occasions, weddings, proms, and military events.
2. How many pins do I need to pin a boutonniere?
One pin works for short events. Use two pins for weddings or events lasting several hours.
3. Can I pin a boutonniere without damaging the suit?
Yes, as long as you scoop the fabric at an angle (not push straight through) and go through the stem as your anchor, the fabric stays intact.
4. How long before the wedding should I pin boutonnieres?
Pin them no more than 30–60 minutes before the ceremony. Any earlier and the flowers may begin to wilt or droop.
5. What if I bend the pin or it won’t go through?
Stop and get a fresh pin. Forcing a bent pin tears fabric. Boutonniere pins should glide through the stem with gentle pressure.
6. Can I pin a boutonniere on a vest instead of a jacket?
Yes, but it’s less common. The same placement rules apply left chest area, 4 inches below the shoulder.
7. What do I do if the boutonniere falls off?
Re-pin using the same technique. Keep one or two spare pins in your pocket for exactly this situation.
