Everything You Need To Know About Sweaters: Cotton, Merino Wool, and Cashmere
As fall and winter roll in, the days get cozier, and so does our wardrobe. Maybe you’re finally ready to replace that black cardigan you’ve been living in for years, or perhaps you’re on the hunt for a chic white cardigan to wear for a special occasion. Either way, once sweater season hits, we’re suddenly bombarded with choices: cotton, merino wool, cashmere… but what’s the difference, and which one should you buy?
Let’s break it down:
Cotton
Cotton is made from the soft fibres of the cotton plant, which are spun into yarn and then woven into fabric. Known for being breathable and durable, cotton is one of the most versatile textiles out there. Depending on the weight, cotton sweaters can range from lightweight and airy to thick and cozy. A cotton oversized sweater makes the perfect transitional layer—you can throw it over a tee or slip it under a jacket for effortless style. A classic cotton white sweater, on the other hand, is timeless and works beautifully on its own during cooler days. That said, cotton doesn’t trap heat as well as wool or other insulating fibres. On very cold winter days, you’ll want to use it as a layering piece rather than relying on it for warmth.
Pro Tip: Always check the label. Aim for sweaters made of 100% natural fibres, or at least 50% or more. Some brands sneak in a high percentage of acrylic (essentially plastic) and still charge $75 or more. Save your money for quality pieces.
Cashmere
Cashmere feels like luxury in sweater form. This fabric comes from goats, and it’s buttery soft, lightweight, and unbelievably warm. Because goats only produce a small amount of this fibre, cashmere is usually pricier than regular wool.
Most sweaters marketed as cashmere are blends (often 10–30% cashmere mixed with wool). If you want the dreamy feel of 100% cashmere, be prepared for a higher price tag.
And if you’ve ever wondered how to wash cashmere or how to clean cashmere without ruining it—don’t worry, we’ll get there below.
Merino Wool
Merino wool comes from a special sheep (you guessed it—the merino sheep!). Unlike traditional wool, merino fibres are very fine, giving it a soft, smooth feel. It’s breathable, helps regulate body temperature, and even wicks away moisture. Translation? It keeps you warm without the itch. Perfect for layering under your favorite cardigan women styles or even a sleek cardigan womens black look.
