I agree that you would be fine with a well fitting button up with jeans and sneakers instead of a t-shirt for the first meetup. I also have no tattoos so maybe t-shirts fit better with your style because you can present your tattoos? Regardless of what you wear I believe an important thing is how the items fit your body, NO baggy clothes you want people to admire your body not hide it from them. Most important is how you carry yourself or your "vibe".
