Suggested Clothing to bring:

Maui is a very casual place. For the daytime, shorts and tee shirts, with sandals, are the norm. Swimwear is almost essential, given all our water. Walking shoes are useful. Evening wear is slacks and a casual shirt for men; and pants or a simple skirt for women. A light jacket for the evening is a good idea.

Of course, you will also want to bring clothing for your own specific activities, such as tennis or golf or horseback riding. If you plan to go to the mountains or explore the island, you may want warmer clothing - Haleakalea is 10,000 ft. high and gets quite cold in the mornings and evenings.
