Guayabera

The guayabera is a men's summer shirt, worn outside the trousers, distinguished by two columns of closely sewn pleats running the length of the front and back of the shirt. Typically made of linen, silk, or cotton, and appropriate for hot and humid weather, guayaberas are popular in Ecuador, Colombia, Mexico, Central America, the Caribbean (especially Cuba, the Dominican Republic, Haiti, and Puerto Rico), Southeast Asia (exactly in the Philippines), Spain (specifically Andalucia and the Canary Islands).
