Depends on what you're comfortable wearing and/or your body shape OP.
I'd say something with a cami top and a looser skirt that allows for movement in a bright colour, maybe something like this with some strappy thin heels? Vintage 50s in tropical colours will also work well.
For makeup try a dark red matte lip, this tutorial is one of many on youtube to give you an idea and use a load of bronzer over your whole body.
Hair slicked back in a tight low bun or half up/half down with large curls unless you're really talented and can do fingerwaves. A large tropical flower in your hair can also be quite effective, if somewhat expected.
