A frock coat is a man's coat characterised by knee-length skirts all around the base, popular during the Victorian and Edwardian periods. The double-breasted style is sometimes called a Prince Albert (after the consort to Queen Victoria). The frock coat is a fitted, long-sleeved coat with a centre vent at the back, and some features unusual in post-Victorian dress. These include the reverse collar and lapels, where the outer edge of the lapel is cut from a separate piece of cloth to the main body, and also a high degree of waist suppression, where the coat's diameter round the waist is much less than round the chest. This is achieved by a high horizontal waist seam with side bodies, which are extra panels of fabric above the waist used to pull in the naturally cylindrical drape.

The frock coat was widely worn in much the same situations as modern lounge suits and formalwear, with different variations. One example is that a frock coat for formalwear was always double-breasted with peaked lapels; as informal wear, the single-breasted frock coat often sported the step, or notched, lapel (the cause of its informality), and was more common in the early nineteenth century than the formal model.

Captain Jack Sparrow is a fictional character and the main protagonist of the Pirates of the Caribbean film series created by screenwriters Ted Elliott and Terry Rossio, portrayed by Johnny Depp. He is first introduced in the film Pirates of the Caribbean: The Curse of the Black Pearl (2003). He later appears in the sequels Dead Man's Chest (2006), At World's End (2007), and On Stranger Tides (2011). Jack Sparrow was originally conceived as a supporting character. He was brought to life by the actor Johnny Depp, who based his characterization on The Rolling Stones guitarist Keith Richards and cartoon character Pepé Le Pew. He tends to become rather frustrated whenever someone pronounces his name without the term "Captain".

The series Pirates of the Caribbean was inspired by a Disney theme park ride, and in 2006, when the ride was revamped, the character of Jack Sparrow was introduced to it. Jack Sparrow is also the subject of a children's book series, Pirates of the Caribbean: Jack Sparrow, which chronicles his teenage years and the character has also appeared in numerous video games.
