Does your gym have a dress code for its members?

My gym is a full gym, indoor pool, aerobic type classes, spinning, basketball, weights, treadmills, etc. There is a rule that women can not show their stomachs. No bikinis, no bra tops, etc. In my opinion it is being overly strict. Literally, if there is a two inch gap between the end of your shirt and the top of your shorts, you will be spoken to, possibly sent home, definitely they don’t want to have to speak to you twice.

Is your gym the same way? What do you think about such a code?

I am not really concerned whether or not they are allowed to have a code, I am not trying to fight city hall or anything, just wondering if other people think this is extreme. But, if you have an opinion on whether it should be legal or how these rules might come about feel free to share.

Just a little more background my gym is subsidized and run by the city. Members do pay to join, it is not simply open to the public for free. I live outside of the city, so I pay more. Do you think it should be different for government run facilities compared to private?
