I've been using a variation of the recommended scheme; when possible my clothing names start with the figure, then contain a collection name, then go to specific item name. The textures and MAT poses follow the same order; complete item name then a specific MAT name. The downside is ending up with either names that are too long to comfortably display, or names that are as easy to read as US Navy acronyms. As long as your product is in its own folder you can order it with ordinary alpha characters. There is no reason for the exclamation point other than trying to put yourself in front of competitors -- and all it achieves there is confusion and annoyance.
