The Real Story On How Trench Coats Got Their Name

Bet you never knew how Burberry struck gold.

From khaki pants to pea coats, international military has always had an effect on the fashion and style of everyday civilians.

And trench coats -- double breasted, generally oversized coats with deep pockets and a belt -- are known as such today because British military soldiers wore them in the trenches of World War I. But they existed in the years leading up to that war, and would live long after it, thanks to celebrities such as Humphrey Bogart and Marlene Dietrich -- eventually becoming as mandatory to have in your wardrobe as blue jeans or that J.Crew gingham shirt. Here's the story.

The trenches of Europe in the 1800s and 1900s were nasty places to fight for your country. Long, winding tunnels, "they smelled, of both the unwashed living bodies crammed in there and the dead ones buried close by," a Smithsonian article describes it. Exposed to the elements, "[trenches] were muddy and filthy, and often flooded with either rain or, when the latrines overflowed, something worse."

The soldiers, then clad in woolen "greatcoats" -- long overcoats of a thick twill fabric called serge -- were warm but too bulky for agile soldiers.

Obviously, a military unit is going to be interested in clothing that protects its soldiers from the elements -- but in the mid-1800s, the predominant weather jackets were known as Macks, which started showing up thanks to inventor Charles Macintosh around 1823.

Rubberized and inflexible, Macks would keep rain out but your sweat in. Still, they were successful enough to create a market for consumers who wanted jackets that would protect their wearers from the weather.

Enter Thomas Burberry, who at the age of 21 in 1856 launched a new shop where he'd invent a fabric called gabardine in 1879 -- Burberry's was much more breathable and still weather proof.

At around the same time, Aquascutum, a brand whose name translates from Latin into "water shield," invented what it called the world's first waterproof textile. Their "Wrappers" were soon seen on guys who liked to dress up while still staying dry in a rainstorm (the two brands both claim to have invented the trench coat, but The Smithsonian says nobody knows for sure who deserves the credit).

When the British commissioned Burberry in 1901 to make his generously sized overcoat to be a part of its military kits, "it would make his fortune," according to the "Fashion Dictionary," edited by Baldini Castoldi Dalai, which further explains:

"The garment had shoulder straps, a waist belt with rings from which to hand anything a soldier might need in a trench, more small belts to make it a sort of diving suit to protect oneself from water and cold, doubled fabric in the parts most exposed to rain, and many pockets."

Today, still a cornerstone of its business, Burberry's trench coats come in a glut of styles and fabrics -- suede, cotton silk and gabardine, fetching thousands of dollars -- and during WWI, officers forked over £3 and £4 for this good Burberry trench coat, which would have been a soldier's three or four months' pay.

Here, see how much (or little) has changed between the early trench coats and those that are available in Burberry's London collection online today.
