Baseball outfits, also known as uniforms, are typically worn by players on a baseball team. The term 'Nines' is often used to refer to the traditional baseball uniform, which consists of a jersey, pants, socks, and a cap. The jersey usually has the team's logo or name on it, and the pants and socks are usually a solid color. The cap is usually the same color as the jersey, and often has the team's logo or name on it.
