If you already have the add-on then you can do this. Just edit the client.cs and the lines you don't want on, put a // at the very beginning. Iirc funky shirt should be stupidly easy to read. If you want the arms, torso, and hat, leave the lines $pref::Avatar::RArmColor and $pref::Avatar::LArmColor for the arms. $pref::Avatar::TorsoColor for the chest and $pref::Avatar::HatColor is the hat.
