The Peter Pan collar is evocative of children's clothing from the 1950-60s. As Peter Pan never did wear a collar (in the book that is, in the Disney cartoon his tunic had a pointed collar), I'm going to go ahead and make the claim that his namesake clothing feature must be so-called because it is The Collar That Will Never Grow Old.
Its recent revival into mainstream clothing lines (below, versions from The Gap and Topshop) adds an element of vintage charm, no doubt influenced by the likes of Alexa Chung who is frequently photographed in collared blouses, and whose fall 2010 collection for Madewell included dresses and blouses with these sweet rounded collars.
