Winston Churchill started wearing them because of how comfortable they were.\nWhile this may not seem like it was a big deal, it completely changed the way people looked at what we now call the onesie.\n
The “siren suit” was one of the earlier iterations of the onesie.\n
A one-piece garment that covered the entire body, the siren suit was initially designed for use on the way to and in air-raid shelters.\n
This suit addressed and solved the problems of warmth and modesty that came up during night-time air raids in the UK during World War II.\n
Siren suits had a similar style to that of boiler-suits, which were worn primarily by mechanics, brick layers, and similar types of workers.\n
The union suit\n
\n
The union suit was another early version of the onesie; it was essentially a long underwear garment that was comprised of just one piece, similar to the modern onesie.\n
This suit was created in Utica, New York, United States, and first came out as women’s wear during the 19th Century.\nThe union suit was an alternative option to the more constricting garments that were popular at the time.\n
This particular garment kept being used throughout North America into the 20th Century.\nEventually, the popularity of the union suit started to wane and was eventually replaced by two-piece long underwear.\n
Despite the fact that Churchill had essentially endorsed the onesie, it didn’t immediately take off with adults.\n
Onesies were baby-warmers.\n
More often than not people would use onesies as a way to keep their babies warm.\n
By the 1950’s, the baby boom was happening and onesies started becoming extremely popular with parents who needed a way to keep their children snug and comfortable, especially in the colder weather.\n
The onesie finally made its return in the early 1970’s, when a book called “2010: Living in the Future“, a children’s book by Geoffrey Hoyle, boldly predicted that everyone would be wearing jumpsuit style clothes in the future.\nWhile it was said that the patterns of these outfits would vary, they would eventually be universally worn by pretty much everyone.\n
The Present\n
\n
Today, onesies are worn by both men and women of all ages, primarily because of how comfortable and warm they are as lounge-wear.\n
Even many celebrities have been photographed wearing onesies in public as a sign that they are fashionably hit or perhaps just want to be comfortable.\n
Famous Hollywood actors like Brad Pitt have been spotted wearing onesies of varying colors and patterns.\n
