Vintage Ralph Lauren Knit Sweater

The vintage sweaters in your dresser may have humble origins, but they can’t be beaten for year-round fashion.

In the 15th century, sweaters originated as jersey tunics and other knitted shirts designed to keep sailors and fishermen warm. Later, during the 1880s in America, these knitted or crocheted vests or pullovers — in Britain, “jumpers” — were thought to substantially help athletes shed pounds as needed. Sweaters were an ideal garment for sports and outdoor events in the late 19th century. The knit fabric permitted movement but the material also protected against the cold. It wasn’t until the 1920s, however, that sweaters were introduced to the world of high fashion, thanks to pioneering designers such as Elsa Schiaparelli, Coco Chanel and Jeanne Lanvin.

A versatile garment, sweaters go well with most looks — from a casual gathering over drinks with friends to complementing a professional ensemble for the office to a night out at the theater. Simply pair a timeless cardigan with slacks or a skirt and your nicest dress shoes for any occasion, in any season, to tie an outfit together.

Once they were considered en vogue, sweaters were no longer strictly made with natural fibers like wool. Over time, fashion designers introduced the use of softer, synthetic materials. Today, traditional sweaters, such as those made with merino wool, are just as popular as more modern creations, such as the sweater dress. Similar to sweatshirts, sweaters come in all kinds of materials, from light synthetic blends perfect for spring to heavier fabrics, like cable-knit wool, to stay cozy and warm in winter and embrace the Danish concept of hygge.

A crucial factor that goes into selecting the perfect sweater is the material. High-quality wool, such as merino wool, which is soft and breathable, will feel luxurious and keep you warm on even the chilliest of evenings. Alpaca fleece, the fibers of which are native to Peru, offers the same warmth as wool, but an alpaca sweater is going to feel even softer than a merino wool sweater, similar to cashmere. Who doesn’t want a slouchy, oversize sweater made of a mix of mohair, nylon and wool on those subzero East Coast nights?

It’s important to note that wool can be a finicky material, easy to stain or distort and stretch. Synthetic materials are not only lightweight, but a nylon or polyester sweater will also be easier to wash and care for. If you opt for wool, take care of your sweater — fabric shavers, fabric combs and the local dry cleaner are your friends.

Sweaters come in various styles like V-neck, turtleneck and crewneck, which is the most popular style. For those extra cold days, a turtleneck offers added warmth without sacrificing style. Those looking for a casual touch that still emphasizes elegance can opt for a long tunic or scoop-neck pullover.

Maybe Versace or Gucci sweaters catch your eye, or ’90s fashion is your thing and a color-blocked sweater dress or John Galliano cardigan of the era is already a closet staple for you. Perhaps you’d rather opt for a 1970s long-sleeve knit top from Yves Saint Laurent. Either way, you’ll find exactly the black, beige or red vintage sweater you’re looking for in men, women or unisex styles today on 1stDibs.
