Frequently Asked Questions

Can you wear a sweatshirt to the office?

In most professional environments, no. A sweatshirt reads as athletic/casual wear. However, in creative industries or very casual workplaces, a clean, solid-colored crewneck sweatshirt can work. When in doubt, choose a sweater instead.

Is a sweater warmer than a sweatshirt?

It depends on the fiber. A thick wool or cashmere sweater is warmer than a standard cotton sweatshirt. However, a heavyweight fleece sweatshirt can be warmer than a thin cotton sweater. For cold weather, merino wool sweaters offer the best warmth-to-weight ratio.

What's the difference between a sweatshirt and a hoodie?

A sweatshirt is a crewneck pullover with no hood. A hoodie has an attached hood and often a front kangaroo pocket. Sweatshirts are slightly more polished; hoodies are more casual and athletic.

Can you layer a sweater over a sweatshirt?

It's not recommended. Both are mid-layers, so combining them creates bulk and looks unintentional. Instead, layer a sweater over a shirt, or a sweatshirt under a jacket.

What sweater fabric is best?

Merino wool is the best all-around choice: it's warm, breathable, lightweight, resists odor, and many versions are machine-washable. Cashmere is softer and more luxurious but requires more care. Cotton sweaters are best for spring/summer layering.

Are crewneck or V-neck sweaters more versatile?

Crewneck. It works alone, over a t-shirt, over a collared shirt, and under a jacket. V-necks are specifically designed to show a shirt collar or tie underneath, making them less versatile as standalone pieces.
