Traits for a person who is...invisible? Well, let's see... The person might be described as:
- meticulous in his 'appearance' - since he is completely invisible, not just partly invisible
- cautious - since she doesn't want to be seen
- reliable - since he is consistently invisible
- flowery - since she wears lilac-scented perfume you can smell
- musky - if he wears musk cologne
