When it comes to men’s fashion, it’s the small details that make a big difference. One of those subtle yet significant details is the slit in a sport coat for a boutonniere. While often overlooked, this feature is deeply rooted in tradition and adds a sophisticated touch to formal and semi-formal attire. Whether you’re attending a wedding, prom, or black-tie event, understanding the purpose and use of this slit can elevate your style game.
In this article, we’ll explore what this slit is, why it matters, and how to use it properly—so you can wear your boutonniere like a pro.
What Is the Slit in a Sport Coat For?
The Function of the Boutonnière Slit
That small, vertical opening on the left lapel of a sport coat or suit jacket isn’t just decorative—it’s a boutonnière slit. Designed to hold a flower stem, this slit is positioned above the heart, symbolizing love and respect in many cultures.
A Nod to Tradition
Originally, the slit was created to hold fresh flowers during courtship or military ceremonies. Over time, it became a hallmark of elegant menswear, especially for weddings, galas, and formal occasions.
Why Use the Slit for a Boutonniere?
Secure and Stylish Placement
Using the lapel slit ensures the flower stays in place naturally, without the need for pins or clips that can damage the fabric. It’s also the intended, classic placement that tailors design the jacket around.
Better Aesthetics
When properly used, the boutonniere appears to float effortlessly on the lapel, giving a more polished and timeless look than simply pinning it on.
How to Use the Lapel Slit for a Boutonniere
Step-by-Step Guide
- Locate the Slit – It’s typically found on the left lapel, near the collar.
- Check for a Loop – Some jackets include a thread loop behind the lapel to hold the stem securely.
- Insert the Stem – Gently slide the boutonniere stem through the slit.
- Secure It – If there’s a loop on the back, thread the stem through it. If not, a small pin from behind the lapel can help.
💡 Pro tip: For jackets without a slit, a tailor can add one or provide a discreet holder behind the lapel.
Types of Boutonnieres to Use
Not all flowers are created equal when it comes to lapel wear. Choose blooms that are durable, compact, and elegant.
Popular Boutonnière Flowers
- Roses – Classic and romantic
- Carnations – Traditional and long-lasting
- Calla lilies – Sleek and modern
- Succulents – Unique and trendy
- Herbs (like rosemary or lavender) – Fragrant and stylish
Things to Avoid
- Oversized flowers that droop or look bulky
- Delicate flowers that wilt quickly
- Bright colors that clash with the suit
When Should You Wear a Boutonniere?
While common at weddings, there are several occasions where a boutonniere is appropriate:
Events to Consider
- Weddings – Especially for grooms, groomsmen, and fathers of the couple
- Proms and Formal Dances
- Graduation Ceremonies
- Black-Tie Events or Award Galas
- Military Ceremonies or Parades
Wearing a boutonniere is a great way to express personality while showing respect for the occasion.
Can You Add a Slit to a Sport Coat?
Absolutely. If your jacket lacks a boutonnière slit, a tailor can easily add one.
Tailoring Tips
- Ask for a hand-cut lapel slit with a reinforcing loop behind it
- Choose reinforced stitching for durability
- Make sure the position is traditional—just below the notch or peak of the lapel
Adding this detail enhances the coat’s functionality and style, especially if you attend formal events regularly.
Caring for Your Boutonniere and Coat
Boutonnière Care
- Keep the flower in a cool place before wearing
- Mist lightly with water for freshness
- Remove promptly after the event
Jacket Care
- Avoid pinning through the fabric—always use the slit when possible
- If using pins, insert from the back to minimize damage
- Dry clean the jacket if any residue or moisture from the flower transfers
