Bikini: Salinas (bought in Brazil) | Shorts: Theory | Sandals: Banana Republic
Or a bay… depending on how you look at it. Either way, my strategy of unpacking poolside and never moving pretty much went on without a hitch. There were some momentary musings on paddle-boarding lessons, which sadly never took place due to a scheduling mishap (though I must admit I was partially relieved).
My general rule of thumb on beach holidays is to pack as many bikinis as I can possibly squeeze into my carry-on (they are small, though in aggregate they can still bulk up!). This may sound silly or redundant, but there is nothing more unappealing than putting on a wet bathing suit from the day before, so I make sure to leave myself plenty of options! Plus, they conveniently serve double duty in the evenings (best worn under a casual top or a shift dress).
