I often have to take a real hard look at myself to understand my own motivations. Anytime I want to "help" my son, I have to ask if I am really helping or am I trying to relieve my own discomfort. If I was holding on to his clothing, I would have to ask myself if I plan to wear them or am I simply trying to make his life more difficult.
Is there a useful purpose to holding on to his belongings? Don't feel that you have to answer this question on this forum or justify your actions. Answer it to yourself and deal with it accordingly.
