You surely have received information on the events and happenings of the resort well before your trip. Look at each event or activity that you may want to participate in and write down what clothing you would need to wear. For a jeep expedition or a journey into the jungle you would want to have capri-length pants, a T-shirt, a brimmed hat and sneakers. For dinner at an upper-scale resort restaurant, you still can think more casual than dressy--perhaps a tank dress or a sundress would do. If the restaurant information says "jacket required," you should wear a nice cocktail dress and a man would need to wear a sports jacket. Some resort restaurants require men to have a sleeved shirt and proper footwear.
Generally speaking, all-inclusive resorts in Mexico are very casual. On site, you will need bathing suits and cover-ups, shorts, tanks, tees or golf shirts, sneakers, sandals and perhaps a pair of dress sandals or shoes. Evenings and early mornings can carry a chill, so pack a light jacket or sweater. Keep in mind that the sun is very strong, so wear sunscreen and protect your back if you are snorkeling by wearing a T-shirt over your bathing suit.
Being at an all-inclusive resort means that you don't need to carry your purse, so don't worry about taking an extra bag for evening. A small pack is great for off-resort excursions, but you should never carry much cash or wear flashy jewelry. Never wear what you aren't willing to lose.
From the list that you made, tally how many pairs of shorts and tops you will need. If you will be playing golf or tennis, make sure to take appropriate outfits and footwear. You should check the materials supplied by the resort to see if there are laundry facilities; you can take a lot less if you can launder your clothes.
One or two light scarves or bandannas come in very handy for dressing up an outfit, pulling back your hair, wiping a moist brow or neck, creating a quick bandage, or covering your eyes from early morning sunlight in your room. They wash out by hand easily and dry quickly so you can reuse them.
If you happen to be going to one of Mexico's many "clothes optional" resorts, obviously you only need to pack a few items, especially footwear, sunscreen, hats and clothes for venturing off resort property.
Now that you know what to take to wear, relax and plan your excursions.
