Which knit should you choose?

Cashmere and cotton are two perennial favorites in knitwear, and for good reason. Both are comfortable, versatile fibers that can be worn across seasons, but they feel and perform differently.

So, which should you choose? Your ideal sweater depends on the weather, how you plan to wear it, and what you want from the fabric. Here's a closer look at cashmere vs. cotton and where each fits into a wardrobe.

What Is the Difference Between Cashmere and Cotton?

The biggest difference begins with the fibers themselves. Cotton is a plant-based natural fiber valued for its breathability and comfortable feel. Cashmere comes from the soft undercoat of cashmere goats and is known for its exceptional warmth relative to its weight.

Those qualities give each fiber a different place in your wardrobe. Cotton is particularly useful in mild and transitional weather, while cashmere offers lightweight insulation when temperatures begin to fall.

When to Choose a Cotton Sweater

Diamond Pullover

Cotton is a natural choice when you want a sweater with breathability and structure. It works especially well during transitional seasons, cool summer evenings and mild fall days when a heavier sweater would feel like too much.

The Diamond Pullover is crafted in a soft cotton-blend yarn with a relaxed crewneck silhouette and diamond intarsia detailing. It has the familiar ease of a sweatshirt with the texture and finish of a knit, making it an approachable way to bring sweaters back into your wardrobe before colder weather arrives.

Cotton also tends to work well for everyday dressing. Pair a cotton sweater with trousers, skirts or jeans and add another layer only when the weather calls for it.

When to Choose Cashmere 

Maria Crew

Cashmere comes into its own when you want warmth without considerable weight or bulk. Its insulating properties make it especially useful for cool weather and layering.

The Maria Crew is made from 100% cashmere in a lightweight, slim silhouette. Its pullover design can be worn as an outer layer during milder weather or slipped underneath a jacket when temperatures drop.

This is where cashmere can be particularly useful in an everyday wardrobe. Even a relatively fine knit can provide warmth while remaining comfortable beneath other layers.

Is Cashmere Warmer Than Cotton?

Generally, cashmere provides more insulation than cotton for its weight. That means a cashmere sweater can feel warm without needing the heavier construction you might expect from cold-weather knitwear.

Cotton is more breathable and typically less insulating, making it well suited to temperatures that fluctuate throughout the day.

The construction of the individual sweater still matters. Yarn weight, stitch and fit all influence how warm a garment feels, so fiber content is best considered alongside the design of the piece itself.

What About a Cashmere Blend?

St. Germaine

Choosing cashmere doesn't always mean choosing 100% cashmere. Blended yarns can combine characteristics from multiple natural fibers.

The St. Germaine is made from extrafine merino wool and cashmere, combining softness with lightweight warmth. Its open-front silhouette, longer line and hood make it particularly well suited to layering.

A cashmere blend can be a useful option when you're looking for warmth and softness in a more substantial knit.

Which Is Better for Transitional Weather?

Cotton has a natural advantage during warmer transitional days because of its breathability. A cotton sweater can add the texture and coverage associated with fall without immediately committing to a heavier layer.

Cashmere becomes especially useful when mornings and evenings turn cooler. Lightweight cashmere can be layered without adding much bulk, making it easy to carry through the day.

This is also where having both fibers in your wardrobe becomes useful. Start the season with cotton and gradually bring cashmere into rotation as temperatures fall.

Is Cotton Easier to Care for Than Cashmere? 

EXPLORE OUR CARE TIPS

A little-known fact about cashmere is that it does not need washing as often as cotton. While cotton is typically easy to care for, you'll get a lot more wear out of cashmere before you need to wash.

Some cotton knits can be gently machine washed, while cashmere often calls for hand washing or dry cleaning. Knitwear should also be stored folded rather than hanging for extended periods, which can cause a sweater to stretch and lose its shape.

Cashmere may occasionally develop pills where the fabric experiences friction. A sweater comb can gently remove them and help maintain the surface of the knit. Care depends on the individual garment, so the care label should always be your first reference.

Cashmere or Cotton: Which Is Right for You?

Choose cotton when breathability and versatility across mild temperatures are your priorities. It's an easy choice for everyday wear, transitional weather and anyone who tends to run warm.

Choose cashmere when you're looking for greater warmth at a lighter weight. It works especially well for cool weather, travel and layered dressing.

You may find that the most useful wardrobe includes both. Cotton carries knitwear comfortably through warmer days, while cashmere takes over as temperatures fall, giving each fiber its own time and place throughout the year.
