To navigate, surf and swim in the waves being sure not to loose your bathing suit, I wear a one-piece swimsuit in neoprene—efficient and very sexy.
To chill with my girl friends at the beach and to play volleyball, I slip on the Corda bikini by Oxbow. But I am not against going topless, privately, in order to have fewer tan marks.
And I keep the well-cut trikini for evening beach and pool parties.
