I didn’t see it coming, nor did I want to see it, but my niece did, and she was grossed out by a woman parading around the locker room in her birthday suit. Of course, you can’t wear a towel when you’re dressing and undressing, but the rest of the time (doing your makeup and hair, walking to and from the restroom, shower, and sauna), remember: locker room towels are there for a reason, so use them.

Which leads us to our first secret of locker-room etiquette:

· Cover up. I’m thrilled that your body is fit as a fiddle, but not everyone wants to see it. Show off by the pool in your bathing suit.

· Avoid the locker room stare. If you wear a towel at the appropriate times, you won’t have to worry about drawing looks. But if others are into self-display, just ignore them—it’s uncool to stare.
