The sources provide details on 27 different types of necklines, including descriptions, who they are best suited for, and styling tips. Here's a breakdown of some of the necklines:

• Crew Neck: A simple, round neckline that sits below the base of the neck, often found on casual tops. It draws attention to the face and shoulders and is ideal for those with slender shoulders, a long neck, or a large bust. A classic crew neck can add width to the upper torso, making it suitable for pear-shaped body types.
• Scoop Neck: A rounded neckline like a crew neck, but it sits lower. The scoop shape lengthens the neck and highlights the collarbone and décolletage and is flattering for those with small busts, shorter necks, or angular faces. It can add curves to a boxy body shape while lengthening the neck.
• Boat Neck: Also known as a bateau neckline, it's a wide oval that sits below the collarbone. It accentuates the shoulders and neck, creating balance for those with narrow shoulders or wider hips. It is ideal for people with narrow shoulders, long necks, and oval or round faces, and it can add width to the upper body for a pear shape. High boat necks are called Sabrina necklines.
• V-neck: Features two lines that form a V-shape and can flatter any body type, but is particularly suited to heart and petite shapes. It lengthens the neck, and can be layered if the neck is too long. A deeper V can balance a larger bust.
• Plunging Neckline: A very deep V-neck, often used in wedding dresses and evening wear. It is ideal for those with larger busts or shorter torsos, as it elongates the body and frames the chest. A plunging neckline can dip from below the bust to the belly button.
• Halter Neck: Wraps around the back of the neck, forming a narrow V-shape. It accentuates the shoulders and draws the eye upward, making it suitable for medium to full busts and wide shoulders, and is particularly flattering for hourglass and rectangular body types.
• Jewel Neck: A high, rounded neckline that sits at the base of the throat. It is ideal for showcasing necklaces and is a good choice for a classy, elegant look. It draws attention to the face and can give the illusion of wider shoulders, making it suitable for pear-shaped figures.
• Collar Neck: Features a rounded collar, often seen in blouses and jackets and can be adjusted using buttons for desired coverage. It is suitable for heart or pear body shapes. Statement collars, like Peter Pan collars, suit those with small busts and rectangle body shapes.
• Sweetheart Neck: A strapless, heart-shaped neckline, often called a princess neckline on wedding dresses. It tends to sit low on the bust and can help to elongate the upper body, making it suitable for those with shorter necks.
• Square Neck: Drops into a square shape above the bust, highlighting the bust and collarbones. It is particularly flattering on an hourglass figure.
• Surplice Neck: Features fabric that crosses over itself to form a V-shape, often seen on wrap dresses. It is especially flattering for apple body types, helping to define the waist and create the illusion of wider hips.
• Split Neck: Features a small gap in the centre, like a split crew neck, and can be closed with buttons. It is most flattering for those with small to medium busts and long necks.
• Mock Neck: A short collar at the base of the neck, found on cold-weather clothing. It is a better option than a turtleneck for those with a shorter neck, and high necklines are flattering for smaller busts.
• Cowl Neck: Loose and draped to create round, U-shaped folds. Lower cowl necks can show off the décolletage, and the look typically draws attention to the face. It is best for triangle shapes and those with a narrow upper body.
