Turtleneck (polo neck) is a garment or neckline cut with a high, closely fitting collar that wraps the neck and is often folded double. Such a collar gives warmth, protects from cold and creates a clean, spare silhouette. The turtleneck became an icon of the minimalist, intellectual style of the 20th century — worn by artists, philosophers and film stars (recall Audrey Hepburn, Steve Jobs), so it is associated with restrained confidence and intellect. A classic turtleneck of fine knit is elegant and versatile, while voluminous knitted ones are warm and cosy. It is worn both on its own and as a layer under a shirt or jacket. Turtleneck is a silhouette of restrained, 'intellectual' elegance, in which a high collar creates a clean, elongated line of the neck, giving a look warmth, concision and timeless, confident refinement.
