While staying at a Mexican resort, you can look your best while still being comfortable. All-inclusive resorts don’t have particular dress codes, but certain general expectations about attire do apply. There will be times when you'll want to dress more formally and other times when your activities will necessitate more casual clothing.
The first determining factor is the season when you’re traveling. In the winter, though temperatures in Mexico will be much warmer than the northern U.S., you may want to have long pants, jeans, or longer skirts and dresses with jackets or sweaters. In the summer, breathable fabrics like light cotton and linen will help keep you cool in the hot daytime.
Around the resort, wearing casual clothing including shorts or pants, T-shirts, tank tops, cotton and knit shirts is acceptable. Dress in temperature-appropriate comfortable clothing. Most visitors to all-inclusive resorts are not local people, so while understanding cultural norms about dress is helpful when you travel into the nearby city or shopping areas, within the resort you are free to maintain your usual personal style.
When you go shopping or sightseeing in the local town, consider dressing more conservatively to respect Mexican culture. Women should avoid low-cut blouses or high-cut “short shorts” or mini-skirts, though sleeveless shirts and longer shorts or skirts are fine. Men can wear either shorts or pants and casual shirts.
All-inclusive resorts also offer numerous activities on-site including swimming, beach games, workout facilities, golf, tennis and salons. Check the included- and extra-charge activities, such as golf and water skiing, and plan your wardrobe accordingly.
General workout clothing is of course acceptable in the gym facilities, as well as for the sports offerings. Tennis shoes may be required rather than sandals for running or tennis or in the workout rooms. Scuba diving or snorkeling flippers should be available on-site for use or rent.
Consider a standard rule that shirts and shoes are required in dining rooms for health-code reasons and bathing suits rather than shorts and shirts are required for pools to keep from clogging the filters with clothing fibers. Bathing suits are good choices for beach activities as well as optional water skiing, Skidoo or boating options. You may want to bring water shoes or sandals that won’t slip off easily for more involved water sports.
If your resort has a formal evening dining room or bar, you’ll want to have more dressy evening wear. Special celebrations or functions at the resort might require a button down shirt, tie and dress slacks for men. Nice blouses, skirts or dresses are appropriate for women. Remember your dress shoes to coordinate with your evening clothes. Use your natural style but also spruce up for the special evenings on your vacation.
