Creating a custom List or Collection

Trying to make an ambiguous Item class and instead of using inheritance for each item, I want each item to have a list of attributes that tell game (and player) how it can be used. The problem I'm facing is that there is a potential for multiple attributes of the same type on the item AND what if the attached attributes conflict with each other in terms of function.

Example: I add an attribute to the item that can allow it to be equipped as clothing. I don't want to accidentally add an attribute that allows it to be thrown like a tomahawk or something.

Granted, the problem is really only a hypothetical and can be avoided by being careful. Just want to save time in the long run.
