Bring a couple of pairs, and you may want to bring one pair of older pants to work in for 'dirty' work. Shorts are not to be worn while working or on the streets, but could be handy around your room or when we go to the beach, so bring a pair or two. Bring about twelve t-shirts and two dress shirts. Also, bring one pair of nice shoes to wear to church. A pair or two of cool cotton pants can be useful.
Jeans are okay.
Sleeveless shirts are not recommended. T-shirts are okay, but you may get more street flack when you wear them. Bring about six t-shirts and two blouses. Bring sandals for the beach. Also, bring one pair of nice shoes to wear to church.
