I am not an English teacher, but in standard NZ English, a basic guideline would be to say that "wear" would be the verb to choose when discussing anything that comes into contact with a person's body. So we "wear" perfumes, contact lenses, shoes, hats, jewellery, etc. Even for electronic gadgets like headphones or earbuds for MP3 players, "wear" sounds more natural and idiomatic than "use". "I can't hear you because I'm wearing my headphones" sounds better than ""I can't hear you because I'm using my headphones".
For anything not placed in contact with the body, "use" would be the first choice in NZ English.
For some of the more subtle usage differences, I'm sure others can expand on this.
