I'm with Sublime on this. I'm taking the LW at her word. YOU are the one claiming the LW MUST be mistaken and she's spouting off about things she can't possibly understand, and calling them by different names because she simply doesn't know any better.Because, like as Abby said, if he was wearing those inappropriate things to the gym, the reactions would probably stop him pretty quickly. He is most likely wearing something that is appropriate for working out at the place where he works out.
It is more likely to be a wife who is being catty about calling gym clothing she doesn't like by the most derogatory terms she can find for them.
And what reactions are you talking about? Some people don't notice or care how others look at them. If you were working out in a gym, and some dude walks in with a girdle and pink spandex, you gonna just stare at him with your mouth open the whole time?
Most likely you're just gonna be like "wow, what a freak," and continue with your thigh-master. And I think most everyone else will react the same way. And again, dude just might not care.
