Can I wear an Astronaut’s helmet to an Astro’s game?

Going to the game Monday night and since it’s Space City Night I wanted to wear an astronaut helmet. Had my dad paint the helmet and make it Astros theme. I’ve seen on tv in the past people wearing helmets but that was during the playoff runs so I didn’t know if MMP allows it now. Don’t want to show up to the game and then be told I can’t wear/bring it in. Any help would be appreciated!
