We just returned from 12 days on Marina. I saw many more sports coats than usual -- perhaps attributable to the weather which was generally in the 50s to mid 60s. More than one gentleman wore suits with ties frequently. However I also saw much more casual dress than in years past. The table next to us one evening in Polo had two young men wearing sweatshirts and jeans. When entering Red Ginger a man in front of us was wearing a short sleeved shirt with shorts and sneakers and was seated graciously. Another evening in the GDR there was a man with sports coat, cargo pants and dockers.
None of this had any effect on my enjoyment of the evening or venues — it was just very different and noticeable. Nor did it change my typical long-sleeved shirt, dress slacks and dress shoes.
