Stephanie Pratt took a dip in the ocean while on vacation in Hawaii yesterday. She donned a striped bikini for the beach day with her family after arriving on the island last week. Stephanie is staying active during her getaway with morning workouts and paddleboard adventures alongside her dad. It doesn't look like her brother, Spencer, made the trip, though other relatives joined in on the fun. Stephanie is past her reality TV days, but she still maintains friendships with her small-screen costars. She was spotted out partying with Lo Bosworth and Lauren Conrad in March and is on the list of invitees to Kristin Cavallari's upcoming Chicago nuptials.
