What to wear?

I am one cramming mommy again. Just yesterday, Joshua arrived home with a memo from the school. They need to be in a Filipinana costume on the 27th for the culminating program of Buwan ng Wika. Aside from that, they also need to bring Filipino food good for 5. The food is no-brainer, I can just go ahead and buy sapin-sapin or any native delicacies readily available in the grocery store. What makes my head spin around is his costume. I dare not want him to wear the common Barong Tagalog nor the Camiso Chino with red pants. My cousin has a vest/pants costume that looks like a Maranao costume. He’ll fit it once I get home and if ever it doesn’t fit, good luck to Mommy!
