Wear whatever you'd like, or nothing at all. I was just passing on what we witnessed during our visit. Nobody will care if you're completely nude at any meal. There was certainly no "dress code". The main reason my wife and wore clothing is that I spent the months leading up to the our visit to N shopping online for sexy sheer coverups that I was going to very much enjoy watching her wear to dinner. They were not "slutwear" by any stretch, just nicely constructed sheer dresses and clothing that we both enjoy. The shopping beforehand increased our anticipation for our visit and also afforded us a lot of fun ordering, receiving and modeling each purchase. Two different female members of the staff complimented my wife on a couple of her outfits, and we both felt that the compliments were genuine and not just to be nice. One asked where we purchased the dress she was wearing.

If you want to be nude, be nude. If you want to dress up, dress up. It's your own vacation.
