No phone, no lights, no motor car, not a single luxury?! Luckily, being shipwrecked on Halloween is way more fun than the real thing, and transforming yourself into Mary Ann from Gilligan’s Island doesn’t require a trip to a desert isle. Start with the top of our Diva White Dot High Waist Bikini, pair it with some retro, high-waisted denim shorts and white sneakers, and tie your hair in pigtails with some red ribbon. Be sure to order a life preserver with the “SS Minnow” on it, because who needs a professor? You can save your own damn life.
