Rio is one of the only places in the world where you’ll feel like a prude in a bikini. Cariocas (Rio residents) hit the sand in G-strings, bras, Speedos, and tiny shorts. Everyone—children, grandparents, the fit, and the not-so-fit—wear as little as possible. Visitors will find a wonderful air of acceptance on the beach. No one leers. No one appears self-conscious. But keep in mind that none of Rio’s main beaches are topless or nudist. Even if your bathing suit covers barely four Band-Aids’ worth of skin, it’s still required. If you want to show nothing but skin, head to the nudist beach, Abrico.
