Turtlenecks and mock necks are two of the most useful sweaters in a cold-weather wardrobe. They look similar on a hanger, but the collar height changes how they fit, how they layer and how they look on you. Here is the difference, and how to choose.
The short answer
- Turtleneck: a tall collar that covers most of the neck and is usually folded over once or twice.
- Mock neck: a shorter collar that stands up around the base of the neck without folding.
A turtleneck is warmer and more dramatic. A mock neck is lighter, easier to layer and more forgiving if you do not like fabric close to your chin.
What is a turtleneck?
A turtleneck has a long, close-fitting collar that is folded down over itself. It covers the neck almost completely, which makes it the warmest option for winter. It looks sharp under a coat or blazer and has a slightly intellectual, classic feel.
Wear it if: you want maximum warmth, you like a clean column silhouette, or you want one sweater that layers under everything. Our Slim Turtleneck Sweater is cut close to the body for exactly that, and the Oversized Chunky Turtleneck Sweater is its cozy, relaxed counterpart.
What is a mock neck?
A mock neck (sometimes called a funnel or half-high neck) has a short collar, usually one to two inches, that stands up without being folded. It frames the neck without covering it.
Wear it if: you find turtlenecks too warm or too tight, you want a polished look that is easy to wear all day, or you want a neckline that works with necklaces and earrings. See our Fitted Mock-Neck Sweater and Mock-Neck Long Sweater Dress.
Which one suits you?
- Shorter neck: a mock neck often looks more balanced, since it leaves more of the neck visible.
- Longer neck: a folded turtleneck looks especially elegant.
- Layering under shirts or blazers: a thin mock neck sits more neatly under a collar.
- Coldest days: a turtleneck, every time.
How to style a turtleneck
- Tucked into high-waisted trousers with a long coat for work.
- Under a sleeveless dress or pinafore for a layered look.
- Oversized and chunky with straight jeans and boots for weekends.
How to style a mock neck
- With wide-leg trousers and loafers for an easy, polished outfit.
- Under a blazer instead of a shirt.
- With gold hoops or a short chain, which the open collar leaves room for.
Don't forget the cardigan version
A button cardigan with a high collar gives you the warmth of a turtleneck with the flexibility of a jacket. Our Turtleneck Button Cardigan and Stand-Collar Button Cardigan can be worn closed as a sweater or open as a layer.

FAQ
Is a mock neck the same as a turtleneck?
No. A mock neck has a shorter collar that is not folded over. A turtleneck has a tall collar that is folded and covers more of the neck.
Is a mock neck warmer than a crew neck?
Yes, since it covers the base of the neck. It is still lighter than a full turtleneck.
Can you wear a turtleneck to work?
Yes. A slim turtleneck in a neutral color under a blazer or with tailored trousers is a classic office outfit.
