Why not
Chess Tournament Dress Code

Although you are Texan so I'm taking this with a grain of salt.
Indeed. All the players should be required to dress like this

Why not
when it comes to restricting people's freedoms you starting with the wrong assumptions

you should dress professional or business casual. and for women the less revealing clothes will be preferable so as not to potentially distract opponents.
Why do the rapid and blitz championship players have to dress like they're going to their grandmother's funeral? Kinda stupid IMO
