A v-neck can also be referred to as a deep neckline or plunge neckline. Some may also call it a scoop neck as it resembles the shape of a scoop turned upside down. Another synonym for a v-neck is a surplice neckline, which is characterized by a wrap-around style that creates a V shape. A keyhole neckline, on the other hand, is a small opening in the front or back of a garment that creates a V shape. A halter neckline can also be seen as a variation of a V-neck, as it forms a V shape around the neck and chest area. Finally, a sweetheart neckline is a classic style that features a V shape that dips into a curved shape at the bust line.
