Ann-Margret got to keep whatever she wanted of the wardrobe created for her by Helen Rose as part of her contract to do the movie.
As pre-release publicity MGM sent costume designer Helen Rose to New York City and Chicago with "25 Fabulous Helen Rose Fashion Creations" from the $250,000 wardrobe designed for the film. The first fashion show was presented at the National Press Fashion Show sponsored by The New York Couture Group in January 1966. A week later the famous Pump Room in The Ambassador East Hotel was the scene for the Chicago show, followed by the world premiere of the film at The Chicago Theatre on January 28, 1966. A vial of the Robert Piguet fragrance "Bandit" was handed out to the ladies for the first three days of the movies run in Chicago.
The New York City premiere was held as a fund raiser for the Huntington Hartford Gallery of Modern Art in the Grand Ballroom of the New York Hilton Hotel on Valentine's Day 1966.
