In Mexico the perfect outfit depends on the destination: During city touring you can find yourself doing a lot of walking so bring a comfortable pair of walking shoes. There are plenty of bars and restaurants so pack for evenings out too. For safety keep your belongings close to you, a messenger bag is a good idea. Visitors at the coast and of the tropical regions should pack summer clothes and of course swimmers. It’s always useful to carry a small first aid kit which includes insect repellent and sunscreen.
