This style can be seen in various garments, including dresses, blouses, and sweaters. The boat neck design is often favored for its elegant and flattering appearance. It highlights the shoulders and collarbone, making it a popular choice for both casual and formal wear. This neckline can be styled in different ways, such as with long sleeves or short sleeves, to suit various occasions.
