There are several different types of necks that can be found on soccer jerseys, including:

V-neck: A V-neck collar is a collar that dips down into a "V" shape at the front. This style is often used on soccer jerseys and is popular with teams that want a more modern look.

Round neck: A round collar is a collar that sits high up on the neck and does not have a fold-over design. This style is often used on soccer jerseys and is popular with teams that want a more minimalist look.

Polo collar: A polo collar is a type of collar that features a fold-over design with two or three buttons at the front. This style is often used on rugby shirts and is popular with teams that want a more traditional look.

Chinese collar: Chinese collar t-shirts have gained popularity in recent years as a fashion trend, with many designers incorporating the style into their collections. They are often seen as a more stylish alternative to traditional t-shirts, and can add a unique touch to any outfit.
