The origins of these iconic outfits

The modern suit has its roots in 19th-century Great Britain. Beau Brummell, a leading figure in dandyism, strongly influenced its evolution toward a more streamlined silhouette. It quickly became a symbol of professional and everyday elegance. Today, it remains a staple of the men's wardrobe, constantly adapting to trends.

The colloquial term costard simply refers to a suit in a more casual way in everyday speech. It often evokes a two- or three-piece ensemble worn every day.

The tuxedo, meanwhile, appeared toward the end of the 19th century. It derives from the "smoking jacket," an indoor jacket worn by British gentlemen to smoke without damaging their clothes. Edward VII helped popularize it by wearing one to dinners. Exported to the United States, it came to be called a tuxedo. In France, it is associated with the "black tie" dress code.

As for the blazer, it dates back to the 1820s in British rowing clubs, such as those in Cambridge. Originally, it was a navy jacket, often blue with gold buttons, more sporty and standalone.

These stories show how each piece adapted to social and cultural contexts. Knowing their roots can help you choose more wisely today.

The technical features that set them apart

The differences go beyond appearance. They involve fabrics, cuts, and details.

The suit (or suit)

A suit consists of a matching jacket and trousers, sometimes with a waistcoat. The fabric is uniform across all the pieces. The lapels are made from the same fabric as the jacket, without satin. The buttons are classic. It offers great versatility, from the office to semi-formal events. The cuts vary, from slim to more comfortable, depending on current trends.

The tuxedo

A tuxedo is more formal. Its lapels are covered in satin, as are the buttons and the trouser's side stripe (braid). The jacket often fastens with a single button. It is worn with a bow tie and a special shirt with a wing collar. Reserved for evenings, it embodies gala elegance.

The tuxedo is clearly distinguished from the classic suit by its satin accents, which catch the light with refinement.

The blazer

A blazer is a jacket worn on its own, with no matching trousers required. Often made of navy or black flannel, it may have metal buttons. More casual, it pairs easily with jeans, chinos, or contrasting trousers. It occupies a middle ground between a formal suit and a casual jacket.

Here's a comparison table to make things clearer (data synthesized from recent sources on dress codes):

Criteria	Suit / Suit	Tuxedo	Blazer
Composition	Matching jacket + trousers	Matching jacket + trousers	Jacket alone

Formality level	Professional / semi-formal	Very formal (evening)	Intermediate / smart casual
Typical occasions	Office, daytime weddings	Galas, black-tie evenings	Outings, business casual
Trousers	Matching is required	Matching with satin braid	Contrasting is possible

When to wear each outfit?

The choice depends above all on the context.

For a day at the office or a job interview, opt for a classic wool suit in gray or navy blue. It conveys seriousness and competence. Statistics show that men are investing more in versatile pieces: the men's clothing market in France reached around 9.7 billion euros in 2025, with moderate growth driven by sustainability.

A tuxedo is reserved for evening events: evening weddings, galas, or gala dinners. The "black tie" dress code often requires it. Avoid wearing it during the day or for everyday occasions.

A blazer stands out for its versatility. Wear it with jeans for a casual dinner or with light-colored trousers for a semi-formal event. It lets you mix styles effortlessly.

A good blazer transforms an ordinary outfit into a polished look.

We offer a variety of options suited to these occasions. Discover our men’s suits collection to find the style that’s right for you.

How do you choose and care for these pieces?

Fit is essential. A well-fitted jacket defines your silhouette without feeling tight. Always try on several sizes. Choose quality fabrics such as Super 150s wool for impeccable drape and breathability.

Looking after your clothes makes all the difference. Have your suits and tuxedos dry-cleaned. Store them on wide hangers. For more casual blazers, regular care is often enough.

The 2026 trends highlight looser, more comfortable cuts, along with a return to rich textures such as velvet and tweed. Bold colors, like greens and pastels, are gaining ground.

We create pieces that keep up with these trends while remaining timeless. Explore our tuxedos for your upcoming evenings out.
