Several things distinguish a Peter Pan collar from other types of shirt collars. The first, and most distinctive, is the rounded edges of a Peter Pan collar. The edges of the rounds may meet or overlap, or there may be a gap between them. The collar also tends to be small and unobtrusive, as well as close fitting. Typically, a shirt or dress with a Peter Pan collar is modest, since the collar hugs the neck, not leaving room for display of décolletage or cleavage.

The name of the collar is a reference to Peter Pan, a fictional character who lives in Neverland in the novel of the same name, written by J.M. Barrie in the early 1900s. The story is a fairytale about a little boy who never grows up, and the Peter Pan collar is intended to evoke the same fairytale sense of eternal youthfulness. On clothing for young girls, the Peter Pan collar is a perennial favorite since it is a classic, simple look. On older women, the Peter Pan collar is often a subject of debate in the fashion world, with many women either loving or hating it.
The shape and name of the Peter Pan collar appear to have originated in the mid-twentieth century. The design became very popular for school uniforms, and began to spill over into popular culture. Despite being named after a masculine character, the Peter Pan collar is associated primarily with feminine wear, and rarely appears in men’s fashion.
