Karen,
Actually there was quite an array of clothing on passengers and crew. My room steward was in a mini skirt, halter top, and spike heels with her life vest. Due to the lack of lights, my husband was in a stylish RSSC bathrobe as well as was the man across the hall. I put together long pants,a sleeveless top, and tennis shoes as we had no air and it was a bit hot, and they say you need to be prepared for all types of weather. Some got dressed up in their finest, had their handbags, jewelry, passports, etc. It was very interesting the different directions people went. Some never poked their heads out of their suites. We never had to leave our suites nor was it required we get dressed, but some felt we should be prepared. Guess we were remembering the Girl Scout/Boy Scout motto of "Be Prepared." Throughout I never doubted things were under control and we would all be fine.
