When it comes to choosing the perfect suit, the cut you choose can make a big difference as to how formal it feels.
If you’re getting ready for a special occasion, or even a wedding, one of the first decisions you’ll need to make is whether to go for a double-breasted or single-breasted suit.
While both styles may have their place in your wardrobe, they send different messages in terms of formality and sense of occasion. It’s also important to find the right cut to suit and flatter your build and body shape.
What’s the Difference Between the Two?
Cut, Buttons and Silhouette
The main difference between single and double-breasted suits lies in the jacket’s front and how it fastens.
A single-breasted suit features one row of buttons (typically two or three), with a narrow overlap of fabric. It offers a clean, understated look that you can wear pretty much anywhere, including business meetings, social events and smart-casual occasions.
A double-breasted suit has a wider front overlap, and has two vertical rows of buttons, although only one row is functional. The other is just for show, to create that classic double-breasted look. This creates a more structured, stylish silhouette and instantly adds a splash of sophistication and elegance.
Which Suits Slim and Broad Builds?
When buying or hiring suits, you need to think about your build. Some cuts and styles will flatter different body types more than others.
If you have a slim or athletic build, you’ll find the double-breasted style suits you very well. The extra structure can add bulk and emphasise the chest and shoulders, creating a broader, more balanced look.
Those with a broader build, however, may find the single-breasted style more flattering. Its narrower shape offers a sleeker line, which can also make the torso appear longer, especially when worn unbuttoned.
That said, a well-tailored double-breasted suit can still look fantastic on a larger or broader frame. It all comes down to getting the perfect fit. And remember, you’ll need to wear it properly too.

How Formal Is a Double-Breasted Suit?
Traditional Vibes with a Sharp Edge
The double-breasted suit has long been associated with classic menswear elegance. It was popularised in the 1930s , where the style was often worn by royalty, politicians and high-powered businessmen. It has an distinctive old-school charm but with the right tailoring, it can also feel current and stylish.
In terms of formality, a double-breasted suit is generally seen as more formal than its single-breasted counterpart.
When to Wear a Double-Breasted Look
Formal clothing can sometimes be tricky to wear, as you might worry about being overdressed. If you have a special event to go to though, a double-breasted suit is the perfect choice. It’s a great look for business galas and conferences, award ceremonies and big occasion parties held at a venue.
And can you wear a double breasted suit to a wedding? Absolutely – this look is tailor-made for stately home weddings and glamorous evening receptions. Just look at @jadondiass_ from TikTok:

Whenever you want to make a strong, confident impression, reach for your double-breasted suit.
When a Single-Breasted Suit Is the Smarter Choice
More Versatile, Less Intimidating
The single-breasted suit is the all-rounder of men’s tailoring. It’s versatile, timeless and adaptable for both formal and semi-formal occasions. From office meetings and cocktail parties to weddings and dates, you can dress it up with a tie or down with an open collar.
Because it doesn’t have the pronounced structure of a double-breasted jacket, this style can feel more approachable and contemporary. It’s a particularly good choice if you’re not used to wearing suits regularly, but still want to look smart.
Best for Modern Weddings and Semi-Formal Events
Single-breasted suits are an excellent choice for:
- Daytime or summer weddings
- Cocktail parties (or events with a cocktail party dress code)
- Smart casual events
- Business wear.
They’re also easier to accessorise than double-breasted suits, which makes them a great canvas for showing off your personality. You might want to choose a bold tie, statement-belt, a patterned pocket square or standout shoes – whatever suits your personal style.
Which One’s Right for Your Big Day?
Body Type Considerations
The ideal wedding suit should flatter your body shape, be comfortable to wear and make you feel confident all day. If you’re tall and slim, a double-breasted suit can enhance your proportions beautifully. It creates a sense of width and presence that’s perfect for a groom taking centre stage.
For broader or more muscular builds, a single-breasted style may be best – as it’s often easier to get a good tailored fit without restricting movement. It provides more freedom, especially if you plan to hit the dance floor later in the evening!
Whatever your build, remember that the right tailoring and fit can make either suit style look exceptional.
Matching the Suit to Your Wedding Style
You’ve found a suit that fits like a dream, but you also need to make sure it fits in well with the rest of your wedding – from the dress code and venue to the colour scheme and groomsmen’s outfits.
For example, imagine you’re planning a black-tie winter wedding at a grand venue. For this kind of glamorous formal wedding, a dark, double-breasted suit with a peak lapel could be just perfect.
Opting for a relaxed outdoor ceremony or a beach wedding instead? A light-coloured single-breasted linen or cotton suit will look sharp without going overboard.
Ultimately though, the right suit for your wedding comes down to you – your style, what you feel comfortable in and what look you envisage for yourself as you walk down the aisle.
