Character Customization

i've finished all the elements of a typical RPG game but somehow i want my character to change it's looks for example changing it's armor, i just can't somehow instantiate every object to the mesh with some spawn point because some of my animations shows the mesh under it and it look pretty ugly, how do i create a customizable character, i mean having the main mesh cut out to pieces then be auto weighed on the bones once the equipment or armor is equipped, i got this character customization on unity3D resources but it is written on C# i can somehow understand C# but this one is too complex, and honestly i'm weak on creating programs and behaviors on C#. i find javascript more comfortable.
