Pet costumes are specially designed outfits for pets, often used during holidays like Halloween or Christmas. These costumes can range from simple accessories, like hats and bandanas, to full-body suits that transform pets into various characters, such as superheroes or animals. Many pet owners enjoy dressing their pets for fun or to participate in themed events. When choosing a costume, it's important to consider the pet's comfort and safety, ensuring that the outfit fits well and does not restrict movement or cause stress.
