The skirt seems safe.

Looking it all over and weighing your options you quickly decide the only option is the skirt, briefs, combo as it is black and in the water should be indistinguishable from normal swim trunks. With towel also held folded just in half you drape it over an arm to use as a visual shield as well and head to the pool.

As you get there a rather large dude says, "Hey, I wouldn't go in the sauna, there is a naked Ethoin in there, not something you want to see." He slaps your shoulder as he walks by.

"Thanks." You say then add after a tiny pause, "An Ethoin?"

He keeps walking as he turns a bit to call back, "You know, the ones Earthers call Orcs, big, green, ya know, warrior types."

"Oh ya, thanks." You say suddenly wishing you had paid more attention in xenobiology class last year.

As you enter the pool room you see a workout room with 6 machines, all occupied, a big pool with 4 hard core swimmer dudes clearly either racing or doing some kind of workout, a hot tub with a lot of bubbles and the head and shoulders of a rather sexy blonde with a perfect tan, and the telltale light blue skin of an Allucian, this one with short almost military cut, dark green hair. Plus of course the closed light tan colored wooden door of the sauna. "I just need to relax." You say to yourself with a little sigh.
