After an extremely hard week at work, I decided that I wanted to treat myself to something nice. For this something nice, I decided to go to a sauna. I had never been to a sauna before but I had heard a lot of my friends talk about how much they loved it and how relaxing it was for them, so I figured I would give it a try. I got to the sauna and was greeted by a very calm and soothing employee who first directed me to a massage room. I waited and got a great massage which made me very relaxed and ready to go into the sauna. I entered the sauna and the first thing I noticed was that it smelled very woody, almost like being deep in a forest. It was also very hot inside but it wasn't unpleasant. I sat down in the corner and closed my eyes, trying to relax. I spent about thirty minutes in the sauna enjoying the heat and took a shower when I was finally ready to leave. Going to the sauna was the perfect relaxation I needed after my stressful week! 
Question: What should they wear?
swimsuit or nude
