Just off Silhouette 2 weeks ago and can report the only dress code I saw was a Midi print with dots and dashes. There were flip flops, shorts, jeans, T-shirts, swimwear and baseball caps in the theater and restaurants for evenings and chic nights. Where else in the world can one mow a lawn on deck 15 late in the day and then head straight down to dinner and the theater? I think Icona Pop best describes current attitude regarding dress "...I don't care, I love it."
