Don't listen to the inevitable hate you're going to get for your "strict clothing policies".
Your clothing policies are fine, if not more lenient than most workplaces in the world.
Twitch literally has women that blatantly flash their cleavage and whatever else whenever they want and they also rarely get in trouble for things that would get members of the opposite gender banned without a second notice. I've got a perfect example; look up "Alinity defense" and tell me what she's done is justified and "not malicious behavior".
People are going to see your rules and start turning it into a "social justice issue" (I'm implying that this isn't anywhere near severe enough to be considered an issue), but PLEASE try to stand your ground. I know you guys don't want to be Twitch 2: Electric Boogaloo.
Be better than Twitch ever was.
