The origins of these iconic outfits

The suit modern finds its roots in the 19th century in Great Britain. Beau Brummell, a figure of dandyism, strongly influenced its evolution towards a cleaner silhouette. It quickly became the symbol of professional and everyday elegance. Today, it remains a staple of the male wardrobe, with constant adaptations to trends.

The familiar term costard simply refers to the suit in a more casual way in everyday language. It often evokes a two- or three-piece set worn daily.

The tuxedo, it appeared towards 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 adopting it for dinners. Exported to the United States, it took the name tuxedo. In France, it is associated with the "black tie" dress code.

As for the blazer, its origins date back to the 1820s in British rowing clubs, such as at Cambridge. It was originally a navy jacket, often blue with gold buttons, more sporty and independent.

These stories show how each piece adapted to social and cultural contexts. Knowing these roots helps you choose them better today.

The technical features that distinguish them

The differences are not limited to appearance. They affect fabrics, cuts, and details.

The suit

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

The tuxedo

The tuxedo is more formal. Its lapels are covered with satin, as are the buttons and the side stripe on the trousers (trim). The jacket often closes with a single button. It is worn with a bow tie and a specific shirt with a wing collar. Reserved for evening events, it embodies gala elegance.

The tuxedo clearly stands out from the classic suit by its satin accents that catch the light with refinement.

The blazer

The blazer is a jacket alone, without mandatory matching trousers. Often in navy blue or black flannel, it may have metallic buttons. More casual, it pairs easily with jeans, chinos, or contrasting trousers. It occupies an intermediate place between the formal suit and a casual jacket.

Here is a comparison chart to clarify things (data synthesized from recent sources on dress codes):

Criterion	Suit	Tuxedo	Blazer
Composition	Matching jacket + trousers	Matching jacket + trousers	Jacket only
Lapels	Same fabric	Satin	Same or contrasting fabric
Buttons	Classic	Often satin	Often metallic
Level of formality	Professional / semi-formal	Very formal (evening)	Intermediate / smart casual
Typical occasions	Office, daytime weddings	Galas, black tie evenings	Outings, business casual
Trousers	Matching required	Matched with satin trim	Possible contrast

When to wear each outfit?

The choice depends primarily on the context.

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

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

The blazer shines through its versatility. Wear it with jeans for a casual dinner or with light trousers for a semi-formal event. It allows effortless style mixing.

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

How to choose and care for these pieces properly?

Fit is essential. A well-fitted jacket shapes the silhouette without tightening. Always try several sizes. Favor quality fabrics like Super 150 wool for a flawless drape and good breathability.

Maintenance makes 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, with a return to rich textures like velvet or tweed. Bold colors, such as greens or pastels, are gaining ground.

We create pieces that follow these trends while remaining timeless. Explore our tuxedos for your upcoming evenings.
