.............. Yellow Polka Dot Bikini .................

She was afraid to come out in the open (ba-da-dup)
And so a blanket around her, she wore (ba-da-dup)
She was afraid to come out in the open (ba-da-dup)
And so she sat bundled up on the shore

Two, three, four, tell the people what she wore

Notable women in the history of the bikini in the doo-wop era include  the following: Brigitte Bardot; Ursula Andress in Dr. No; Marilyn Monroe; Jayne Mansfield; Gina Lollobrigida; Jane Russell; the Beach Party movies (although Annette Funicello dressed modestly even for the beach); and the Sports Illustratedswimsuit issues.
