Attire looks great! It would be not dressed enough for business/lawyer/consulting, but your look is ideal for office IT, looking professional but ready to crawl around a dusty space to flip a switch where needed.

Show confidence, show that you know what their business is about, and how your qualities and experiences can help their business succeed through you working there. You're there to judge how well you would fit into that workplace, as much as they would be judging you. Compare what being in that team would actually be like, to all the fluff they present themselves with on their website.

During regular days at most companies, IT employees often can get away with single colour t-shirts and track pants, because they're kind of at your mercy. If they complain you can just walk away and not fix their problem.
