You certainly can get away will all kinds of stuff on this earth. Some countries are more flexible than others. The grooming and appearance of the working staff is a good indicator of the most appropriate attire for the location. We prefer to appear like we belong wherever we go. There is always one pair of light long pants that travel well at the bottom of the bag and a blazer somewhere. Off the boat we shave, comb our hair, and put on a shirt with a collar anywhere near sundown.
