Recommend top and shoes for trouser

Hi, everyone. I bought this trouser po and i can't decide what kind of top dapat ko ipartner for this, considering also the event na pagsusuotan ko. Moving up ng brother ko and I'll be the one to accompany him sa stage. Please help me po, I wanna look presentable since old school ko din yon so I might encounter some of my former teachers hehe. Thank you so much po.
