The Evolution of The Three-Piece Suit and How it's Worn Nowadays

What is a Three-piece Suit?

A three-piece suit is simply a suit with three garments:  Jacket, trousers and a waistcoat.

The difference between a two-piece suit and a three-piece suit is just whether you include the waistcoat or not.

A three-piece suit is not limited to using the same fabric or garment throughout the entire outfit.

In this article, we’ll explore how it can be done with variation. A three-piece suit is not merely a three-piece suit.

The Evolution of the Three-Piece Suit

The evolution of the three-piece suit reflects the dynamic interplay between fashion trends and societal norms throughout history.

Originating with the Frock Coat in the 18th century, formalwear epitomized prestige and status, evolving into the sleek Morning Suit of the 19th century. As the 20th century dawned, the Lounge Suit emerged as a more relaxed alternative, blending style and comfort.

Today, the modern three-piece suit combines elements of formality and versatility, remaining a timeless symbol of classical menswear. Its enduring appeal lies in its ability to adapt to changing times while retaining its inherent elegance, making it one of the most formal attires a man can wear.

The Frock Coat

During the Victorian era, spanning from 1837 to 1901, the frock coat emerged as a staple in men’s fashion. Resembling today’s overcoats, it had a single vent at the back and could be single- or double-breasted. The length, reaching down to the knees, exuded formality, with the double-breasted variation earning the moniker “Prince Albert.”

The Frock Coat was the everyday attire for most men during that era, a crucial detail considering the absence of central heating. The length of the coat and waistcoat was intentionally long to provide warmth while maintaining a formal appearance. Additionally, the waistcoat played a vital role in the ensemble, contributing to both style and insulation.

Over time, the frock coat split into two distinct styles: the morning coat, retaining its tails for formal daywear, and the lounge suit, shedding tails for a more relaxed vibe. Nowadays, the morning coat is reserved for exclusive events, embodying timeless elegance and social prestige.

The Morning Suit

As the 19th century progressed, the Morning Suit became the go-to attire for daytime formal occasions. A successor to the Frock Coat, it preserved the essence of formality while embracing evolving fashion sensibilities. With its sleek silhouette and refined aesthetic, the Morning Suit became synonymous with sophistication, favoured by the aristocracy and elite.

At the renowned Royal Ascot event, people wear Morning Suits as part of the tradition. Among the horse racing and socializing, the Morning Coat is a common sight, reflecting the event’s long-standing customs. With its classic style and formal appeal, the Morning Suit adds a touch of sophistication to the occasion, capturing the essence of tradition and high society at Royal Ascot.

The Lounge Suit

With the dawn of the 20th century came a shift towards more relaxed dress codes, leading to the rise of the Lounge Suit. Characterized by a matching jacket, trousers, and waistcoat, it offered a blend of style and comfort suitable for various occasions. The Lounge Suit’s versatility and practicality propelled it into mainstream fashion, marking a departure from the rigid formalities of the past.

The lounge suit, simply often referred to as a “suit”. The lounge suit emerged as a more informal alternative to formal attire, such as morning coats or tailcoats, and has since become a cornerstone of men’s fashion across the globe.

Will we ever transition away from the “final” product we’ve currently reached? Has the traditional three-piece suit cemented its place, or will it gradually lose its power, formality, and character in the future?

How the three-piece suit can be worn nowadays

Dressing it up

Opting for a waistcoat that matches the suit jacket and trousers looks dressier than choosing an odd waistcoat.

Choosing an odd waistcoat for your wedding can easily be done. Most gentlemen selects what is called a brocade vest. Brocade is a woven fabric with a raised figured or floral design added during the weaving process.
Or you could simply opt for a waistcoat in a lighter colour such as light grey, beige or off-white.

Polished and darker-hued shoes – like dark brown or black dress shoes in polished leather – create a more formal aesthetic than say, bright suede loafers. A general rule of thumb is; the fewer noticeable details a leather shoe has, the more formal it is. Examples of formal dress shoes include Oxfords, Wholecuts, Bluchers, Derbys and arguably Brogues.

Tie choice and adding accessories like a stylish watch and a pocketsquare can also play up the level of formality.

Dressing it down

To dress a three-piece down, you could opt for a waiscoat that differs in color from the rest of the suit. Brighter suit colors are also generally considered less formal. You could also ditch the blazer if it’s warm enough in the office.

Choosing dress shoes of brighter colors, or even deviating from brown and black altogether, in favour of navy or perhaps beige shoes, also bring a more casual vibe. Examples of more casual dress shoes include Loafers, Moccasins, Monk Straps and Chelsea Boots.

Tie-wise, you could replace the shiny satin silk with cotton, linen or wool ties with patterns, larger weaves or rougher texture.

The most effective way to add flair to your three-piece suit is by incorporating an odd waistcoat or pairing matching trousers and waistcoat with an odd sports jacket. By doing so, you showcase your knowledge in combining fabrics and elevate your sartorial game even further.

Wearing a three-piece will look more dressed up and formal than a two-piece suit. This is why you’re more likely to see one at a wedding or at other dressy environments. You can either play into that, or try to dress it down, as to not come off as overdressed.
