What is smoking jacket? How to use in English

The smoking jacket, also known as a dressing gown or a robe de soirée, can be traced back to the Victorian era in England. Its origin lies in the desire for gentlemen to smoke cigars or pipes in a more relaxed and comfortable setting than the formal drawing-rooms of their homes. The smoking jacket became popular among the upper class in the late 19th century. At the time, smoking indoors was not accepted in most spaces, except for private smoking rooms known as "smoking censuses." Men would wear a jacket over their evening attire to deter others from noticing their smoking habit. Soon after, smoking jackets became an essential part of the men's wardrobe as they could wear them in the comfort of their natural surroundings like lounges, billiards areas, and libraries. The smoking jacket's design is similar to a dressing gown, but unlike the latter, it has details that contributed to its initial fame. Its sleeves are narrow, and its waist is tightly fitted to accentuate the torso. Its collar, cuffs, and belt often featured silk velvet, felt, or plush material, which gave it an air of sophistication. The jacket's color scheme was predominantly dark and rich, featuring colors such as brown, burgundy, and green, which helped camouflage tobacco ash and residue. In conclusion, the smoking jacket's origin was grounded in the need for men to smoke in privacy, and over time, it became a fashion statement that embodied luxury and refinement. The jacket's historical significance and aesthetic appeal have continued to thrive in contemporary society, with the trend's influence prevalent in modern-day fashion, such as velvet blazers and wool robe coats.
