How to get system with custom outfit/avatar load on game joining

Does someone have or know where to get a system which simply allows me put all set items I can on avatar, including animations and rest of things till accessories, but it has to load on specific profile ID I put and when you join it automatically applies on you list in code of outfit elements for you and others to see.

I would THANK anyone a lot to help me figure this out, because I am no big into scripting, but it sounds like something should be around already (I at least I hope so).
