Beach Babes from Beyond (1993)

Three stunning alien teens, Xena, Luna, and Sola, borrow their father's retro spaceship for a cosmic adventure to find brainy Earthlings on planet Beta 45. However, their journey takes an unexpected turn when they run out of fuel and crash-land near a California beach community. There, they befriend two Midwestern guys, Dave and Jerry, who are staying with Dave's laid-back, surf-loving uncle Bud. Together, they enter a beach bikini contest to win prize money and save Bud's beach shack home from eviction.
