Actually, ano problema dito? Nung high school graduation ko, naka sablay yung isang teacher ko kasi UP grad siya kahit hindi UP related ang HS ko. It's a graduation so he wore his alma mater's graduation attire.

Same with other teachers na may ibang designs sa toga like a hat or a special sash, sinusuot nila yun.

I think there's nothing wrong with going to a non-UP graduation wearing the sablay. Personally, ayoko lang magdraw ng attention, and a sablay in a sea of togas does stick out because that's inevitable. I wouldn't wear a sablay just because shy akong tao and ayoko tumingin sa akin ang mga tao, pero wala namang kaso kung mas bongga lang ako hahahah.
