How do I make the player change appearance based on the team?

Hi! I'm asking this question because I have literally no clue what to do. I tried to use some tutorials, but they didn't work. Can you please help? (I have a humanoid named after a team. Let me know if I need to add more for each team.) Thanks. :3

When you switch someone’s team, right under it add code that’ll change the player’s Shirt, Pants, or hat. If you want to add something then I recommend using the :LoadAsset() function. For more info about it check here: LoadAsset
