Fred Flintstone or Fredrick J. Flintstone is the popular character from the animated series, The Flintstones. This modern caveman is a popular costume theme suited for any occasion. An adult male may deck up in an orange coat or patterned dress with a blue necktie, bare shoe covers and an attached collar. Your getup remains incomplete without a Fred Flintstone wig. You may ask your partner to dress up as his wife, Wilma Flintstone by wearing a white one-shouldered outfit, a matching wig and of course her iconic pearls. Children too may choose the Fred and Wilma theme for fashion shows.
