A suit is a uniform. In a more practical sense, it's a means of directing creative energy away from irrelevant causes, such as self-expression, and enabling you to put undivided focus on your work items, the processing of which benefits the business.
If everyone is in a suit, there can be no games to out-dress the rest of the playing field. The only differentiator is the price of the suit, and that story-line unfolds neatly along the sub-ordination divides. The CEO wears the most expensive suit.
Being the tech-oriented minion, you can get away with wearing a just-so suit, which is just fine by you as well. Honestly, who wants to fashion-shop for a freaking suit? The suit surely has to be the most drab and boring garment in the history of clothed mankind.
