Bermuda is a British Overseas Territory, and retains many elements of that heritage.  The island enjoys a nice blend if island casual and British formality.  Bermuda lies 1000 miles to the north of the Caribbean, and some 700 miles off the coast of the Carolinas. 

Bermuda shorts are a sight to see for the uninitiated.  These long shorts (sounds like an oxymoron, but they run almost to the knee) are considered formal wear when worn with a coat and tie.  It's a bit strange a first, but men will appreciate being freed from wearing long pants in the heat.
