1. 17th century: Forerunner of court dress
In the British and French courts, men wore ornate coats (coats), waistcoats (waistcoats) and breeches.

This is the prototype of the modern three-piece suit, but at that time there was more emphasis on decoration, rich colors, and luxurious materials

2. Late 18th - early 19th centuries: The rise of the "gentleman's dress" in England
The British upper class began to simplify their clothes and emphasize "understated elegance".

An important figure was Beau Brummell, who popularized the style of dark dresses, white shirts, and tie scarves, with an emphasis on tailoring and neatness.

3. Mid-19th century: The prototype of the modern suit
The modern term "suit jacket" was introduced.

Trousers gradually replaced breeches, with a tight waist and a clear shoulder structure

4. 20th century: Western suits became popular all over the world
With colonial expansion and industrialization, suits were introduced from Europe to Asia, America and other places.

The American two-button suit became the standard.

Localization of countries: such as Japan's integration of traditional elements, China also widely adopted suits as formal wear during the Republic of China.

5. Modern: diversified and fashionable
Suits are no longer limited to formal occasions, with changes such as casual suits, slim-fit styles, and lightweight fabrics.

Women's suits have also become common workplace wear.
