I used to wear a shirt and tie with shorts to the first job I had after graduating college. It was certainly comfy and judging by your avatar it's hotter there than where I am so go for it!
It is a good rule in life never to apologize. The right sort of people do not want apologies, and the wrong sort take a mean advantage of them. P. G. Wodehouse (1881 - 1975), The Man Upstairs (1914)
