A waistcoat or vest is a sleeveless upper-body garment worn over a dress shirt and necktie (if applicable) and below a coat as a part of most men's formal wear, and as the third piece of the three-piece male business suit.

A waistcoat has a full vertical opening in the front which fastens with buttons or snaps. Both single-breasted and double-breasted waistcoats exist, regardless of the formality of dress, but single-breasted ones are more common. In a three piece suit, the cloth used matches the jacket and trousers.

Before wristwatches became popular, gentlemen kept their pocket watches in the front waistcoat pocket, with the watch on a watch chain threaded through a buttonhole. Sometimes an extra hole was made in line with the buttonholes for this use. A bar on the end of the chain held the chain in place to catch it if it were dropped or pulled. Now waistcoats are worn less, so the pocket watch may be more likely be stored in a trouser pocket.

Wearing a belt with a waistcoat (and indeed any suit) is not traditionally correct. The waistcoat instead covers a pair of braces (suspenders in the U.S.) underneath it, to give a more comfortable hang to the trousers.

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.
