Three women, three different situations: Whitney (Williams), a rich girl who leaves her groom at the altar; Una (Vivian Blaine), a shopgirl whose desire to marry is continually thwarted by the duty assignments of her sailor boyfriend; Mary Kate (Joan Evans), who was left at the altar by a hesitant fiancé. Soon, all three women report for induction at the Great Lakes Naval Training Station and end up roommates. What follows is a frothy and fun musical buoyed by a chipper cast and seven tunes by Ralph Blane and Harry Warren. Skirts Ahoy! features two swim numbers with Williams and a star turn by Debbie Reynolds and Bobby Van, who sparkle in a special song-and-dance routine to “Oh By Jingo!” Ahoy, indeed!
