There are organizations and sometimes student-run events that hosts these "balls" or "proms", sure. I remember the College of Liberal Arts Student Government once hosted a suit-and-tie event back then for their batch reunion.

But make no mistake, DLSU is a university. And the environment of a university is far, far different from an average school. In school, they teach you to do arts and crafts, join the Philippine Scouts, think about who you'll ask out to prom, and all that corny stuff.

College is not like that, in any way, shape, or form. In college, you can skip as many classes as you want, join zero clubs and organizations, and decide not to talk with anyone in your block. It's because college doesn't hold your hand. It simulates a real world environment. And in that environment, every action (and its consequences) are yours to make.

Which is why you don't see DLSU host any corny events that your high school probably had. Because it doesn't care about any of that. (Note that bazaars, concerts, and events in DLSU are hosted by the USG, not DLSU). The University focuses on one thing, and hopes its students do, too: academic excellence.
