Different Kinds of Necklines
The image below features 26 different necklines.
NB. The Jewel neckline is also also the T-shirt neckline or crew neck. The Boat neck is also called the ‘Bateau’ neckline.
The neckline can frame the shoulders, neck and face, and change their apparent width, height and angularity. It is generally advised that the neckline shape be chosen to balance the wearer’s natural features. Thus, a face with round curves is well-framed by an angular (linear) neckline and collar, whereas an angular face is softened with curves. Similarly, a short neck and face will appear lengthened by necklines with strong vertical (or nearly vertical) lines, such as a plunging V neckline (or a long knotted scarf or necklace); conversely, high necklines such as the jewel or turtleneck types balance long faces. Broad shoulders can seem more narrow with style lines that converge inwards (e.g., the halter neckline), whereas pear-shaped figures can be balanced by diverging or horizontal lines, e.g., an off-the-shoulder or boat neckline.
