For travel I like many of the hiking clothing. For the most part they are light, easy to clean, and durable. In the last few years many are offering fashions that are more resort oriented but there are many choices. While I have others my two favorite travel shirt brands are Exofficio and Mountain Hardware. Exofficio also makes great pair of underwear. As far as pants goes Tilley pants are the best. They look nice, easy to clean, dry quickly, wrinkle resistant, and durable. There is also a secret pocket that makes reduce the chance of theft or accidental loss.
While I consider my dress mainstream conservative what the Europeans think of my dress is of no concern to me.
