I own about two dozen of these Men's Guayabera Short Sleeve, Casual, Snap Shirts. I thoroughly enjoy and appreciate wearing them. They are very comfortable, high quality, very elegantly embroidered shirts with snaps disguised as buttons! Both the fabric and the workmanship are top quality within the regions that they are so prevalently worn.I travel extensively year round. There are times when I stay in an area for an extended length of time. If I am in Africa, the Middle East, the Mediterranean, the South Pacific, India, or S.E. Asia, I need to be comfortable. I want to blend in as much as possible culturally and still look professional, yet casual. This style of shirt completely fills that criteria.Most of the places that I just listed are extremely warm and humid for extended periods of the year. Shirts with ties, sport jackets, and business suits are not at all practical in these climates. In Guayabera short sleeve shirts, however, that are manufactured with the high percentage cotton fabrics that breath, I can look stylishly elegant, and culturally relevant professionally with my attire.In many cultures these shirts are considered to be more of a formal manner of dress than the western culture business suit! They are most assuredly more comfortable than a western culture formal attire!!
