Help with drawing / deleting objects

Hello, I’m doing my first project in Unity for school, and I have good knowledge of c++, but not c#. Basically I’m creating an app that is going to display different clothes on a mannequin. Right now I have my scene set up with then mannequin model and I have buttons that the user can swipe through. When the user presses one of the buttons, I need it to display a specific clothing model on the mannequin, and get rid of the existing one if there is one. I know this is probably pretty basic but I haven’t found anything helpful in forums. I was hoping someone would have advice on how to link each button with a specific piece of clothing and having them draw only when the button is pressed.

Look up the Destroy method to get rid of game objects, or else you can call .SetActvie on them with either true or falls to make them appear/disappear.
