"A White Sport Coat (And A Pink Carnation)" is a 1957 country and western song with words and music both written by Marty Robbins.

[6] Robbins recalled writing "A White Sport Coat" in approximately twenty minutes, while being transported in a standard automobile.

[7] He is said to have had the inspiration for the song while driving from a motel to a venue in Ohio, where he was due to perform that evening.

During the course of the journey, he passed a local high school, where its students were dressed ready for their prom.

[citation needed] In the song, the narrator was hoping to go to the prom with a certain girl, wearing a white sport coat and a pink carnation.
