An accessory, such as a bandana or collar, for an animal, such as a dog, is provided. A bandana can have a triangular fabric body. A strap is attached to each of two ends or corners of the body such that each strap forms a loop. An elastic band extends through the loops of the straps and is formed into a closed loop shape. The elastic band non-releasably couples the two straps and therefore the two ends or corners of the body such that the bandana forms an overall closed loop shape. The elastic band can stretch to allow the bandana to slide over the dog's head and to adapt to the size of the dog's neck.
