I think most dressing rooms these days are unisex. Single occupancy and fully partitioned, it doesn't really make business sense to have them designated by sex.
IF!!! they are fully partitioned, with locking doors, yes. Just like many restaurants are now doing (unfortunately), with their restrooms.
Also, an employee should be stationed, at the entrance of said dressing rooms, as well.
Btw.....as per the linked article, and witnessed by many Texans, the unisex Academy dressings rooms are NOT fully partitioned. That’s how creepy guy got his hand holding cam, over to her dressing room.
