Chambray dress and sandals to travel in, 2 swimsuits to alternate drying days, and lots of bright skirts, tops, and shorts to play mix and match with for a new outfit everyday. Throw in some patterns for a tribal island feel and pop some neon where possible.
Most important is the protect yourself from those harmful rays!! Bring great SPF for skin, hair, lips, and great sunnies for the peepers. I add my coveted J. Crew straw hat for fashion and function, nothing will protect the skin on your face better!
Also how cute are those feet jewelry? I always walk barefoot on the sand but this way you can still have some feet flair to make a statement when your shoes are stashed in your beach bag for protection!
