What to Wear: 06/20/08
The third item in Havana is an excerpt from Consuelo Hermer and Marjorie May's book Havana Mañana called "What to Wear.'
Hermer and May warn against the tell tale signs of being a "tourista" when visiting Havana. They offer wardrobe advice for men and women for all seasons. The basic advice is "dress as you would for work at home but in lighter weight fabrics."
Although the specific advice is probably now dated the foundation is still sound for wherever one may travel. Dress for the weather but keep in mind the type of place being visited. If visiting a large well established city, dress formally but in weather appropriate fabrics. Wear more conservative colors in the winter months than the summer months.
Of course, the other option is to do what you darn well please but be willing to be branded a tourist!
