Believe it or not, there is a dress code of sorts at the polling place -- specifically, within 100 feet of it.
"Inside that zone, you cannot electioneer," says Sam Taylor with the Texas Secretary of State's Office. "That means you cannot represent anything on your clothing -- whether it's a pin, a t shirt, a hat, what have you -- in support or against any candidate or measure on the ballot."
The rule, however, has recently changed.
"It used to be the case that you couldn't wear any political apparel whatsoever," says Taylor. "But there was a federal court case that was resolved last year -- a First Amendment case actually -- the changed it to limit it to only candidates that are on the current ballot."
So if you want to wear political apparel from a previous election, that's okay.
"You can wear a Reagan/Bush shirt (or) you can wear a Clinton/Gore shirt -- something from a previous election," Taylor says. "But you can't wear anything for a candidate or a party or measure that's currently on your ballot."
Therefore, if you show up to the polling place wearing an Abbott T-shirt or a Beto hat, you can expect to be given some specific instructions by the precinct judge.
"The presiding judge at a polling place could ask you to cover up your shirt," says Taylor. "They could ask you to take off your button, take off your hat, or in some cases they might ask you to turn your shirt inside out. And if you refuse to do that, you can actually be turned away from the polling place."
What about those red "Make America Great Again" hats -- can you wear those to the polling place this year?
"As far as I know, Donald Trump's not on the ballot, so you can wear those hats," Taylor says.
Electioneering not the only thing prohibited within 100-foot zone
When you move inside the 100-foot zone, you'll want to put your cell phone away.
"When you're within 100 feet of the actual voting machines themselves, you cannot use a cell phone or a camera (or) any sound or audio recording devices," says Taylor. "I know you're excited to vote. I know you're excited to show all of your friends and family that you just voted. But wait until you get at least 100 feet away from the voting stations before you take that 'I voted' selfie."
If you use a cell phone within the 100-foot zone, the precinct judge will simply ask you to put it away.
