The term 'neckline type' can refer to a variety of different styles of necklines. One such style is the V-neck, which is characterized by a neckline that dips down in a V-shape. This style of neckline is popular in both casual and formal attire, as it can be dressed up or down depending on the occasion. It is also flattering for many body types, as it draws attention to the face and away from the chest.
