On one hand you would look more like a legit team, on the other hand if it's too matchy it opens you up for some jokes. So, my two cents would be. Since you already make them, make a few jerseys with either the same layout and different colors, or the same colors with a different layout, or a combination. So you still look like a real team, but you're not wearing the same thing all the time. Good luck with your tourneys.
