Naked locker rooms were well on the decline (at least for youth) in the '90s. I attended a martial arts gym with adults and kids, where men would regularly walk out of the shower naked and change all while holding conversations with each other.

I learned the hard way at band camp in high school that such casual nudity among a single-gender was socially unacceptable among my own generation, and after the first day changed my clothes under my towel like everybody else.
