Which wand should i bring to Harry Potter midnight premiere?

i recently got a ticket to the midnight premiere of the last Harry
Potter movie and of course im dressing up as a hogwarts student and im
trying to decide on which one of my wands i should bring. I have one
that I hand carved from a crepe myrtle branch and it looks amazing and
one that i got from Ollivander's at the Wizarding World Of Harry
Potter. So tell me which wand sould i bring?
