As Andrea said, for a woman bring shorts, maybe lightweight capris, sundresses and a sweater (for the casinos). My husband bought jeans the first year and never again. He just wears khaki type shorts. Each year I go, I bring more lightweight things. Its always hard the first year you go someplace new. but after this first trip, you'll know exactly what to bring for your next time there (and trust me, there will DEFINITELY be a next time). You kind of get sucked into Aruba. Once you go, it becomes your yearly trip. The weather is perfect 99.9% of the time. There is always that fluke day or afternoon or perhaps hour where it may not be but that is about it. And each year we stay a bit longer than the year before, lol. Enjoy, you'll be back..
