A Peter Pan collar is a flat, round-cornered clothing collar. It is named after the collar of the costume worn in 1905 by actress Maude Adams in her role of Peter Pan. Since then, it has become a women's fashion item several times, and is particularly associated with little girl's dresses. In 1930s-40s the Peter Pan collar was a standard part of a women's wedding dress and from then on it has been in en vogue. A Peter Pan collar shirt or dress will make you look slightly more mature. If you are wearing a Peter Pan collar shirt you should wear it with jeans not so much shorts. You should also wear a necklace which won't hang out to much and won't take attention off your shirt. In your Peter Pan collar outfit you have to pick yourself which pair of clothing or accessories you want to stand out.
