Studs are small, often decorative fasteners or protrusions that can be found on various items, including clothing, accessories, and furniture. They are typically made from materials like metal, plastic, or leather and can serve both functional and aesthetic purposes. In fashion, studs are commonly used to add style to jackets, shoes, and bags. In the context of animals, particularly horses, a stud refers to a male horse that is used for breeding. These horses are often selected for their desirable traits, such as speed or temperament, and are kept in a stud farm where they can mate with female horses, known as mares, to produce offspring.
