What do Coconut Bras have to do with Christmas?

The countdown is officially on! Only two months until Christmas! Where did 2016 go?!

Every year my family does a "themed Christmas" where you come dressed to the theme! Since there are only two months until Christmas, it is crunch time for finding a good theme and costume for the holiday! Last year my parents hosted and my dad declared it to be a "Formal Christmas" where you came dressed in your best. 2014 was "Hawaiian Christmas" and the whole Minke tribe dawned coconut bras. 2013 was a comfy year where we all wore our PJ's to Christmas at my cousins house! What should my family do this year for a theme? Let me know your ideas in the comments!
