When an article of clothing dates back to the 15th century and is still around today, I would say that it is a style that sticks. The turtleneck sweater's origin is pretty spotty but we do know its original purpose was to keep people warm.
In the 1890s the turtleneck sweater was seen all over town, specifically when people were riding this fancy new contraption called a bicycle. Soon after the turtleneck sweater became a staple in sailor's wardrobes to keep them warm while they were on duty. By World War II it became the official uniform of the US Navy; the trend was then taken around the world.
Fast forward to 1950's when beatniks got a hold of them and rocked the turtleneck with a little black beret turning this simple garment into a cultural staple. Next thing you know fashion icon Audrey Hepburn started wearing a little black turtleneck and the rest is history.
Turtleneck sweaters remain a wardrobe staple today but be warned, you must choose your turtleneck wisely. There is nothing fashionable about wearing a holiday turtleneck or cheap knit turtleneck from Wal-Mart. Opt for a black cashmere turtleneck, you will look effortlessly chic and it will last you a lifetime.
