Cancun is a casual place. You will probably spend most of your time on the beach anyway, thus swimming wear is a must. Shorts and T-shirts is the "dress code." At night jeans, slacks, shirts and polo shirts are welcome in almost every place in Cancun. Only if you are planning on going to an exclusive restaurant then you may need a sport jacket and dress pants.

During the winter months you may want to bring a light jacket because it gets a little cold at night. Well cold in Cancun means anything below 75F.

Other items that you need to bring are hats, caps, sunglasses, sun tan lotion, sun protection and sandals.
