In fashion, a collar is the piece of a shirt or dress around the neck which folds over. The tips may optionally have buttons to fasten the collar down to the shirt for a so-called "button-down" collar.
A collar can also be a piece of material put around the neck of an animal, typically a pet, for control, identification, or other purposes. Flea collars, for instance, repel fleas. Identification tags and medical information is often placed on collars.
The collar on a draught animal is a robustly constructed leather and straw device that is intended to sit comfortably on the animal's shoulders around its neck and support a set of hames that transfer the draught forces from the animal to the traces.
