It really depends. Having a strong character is not determined by looks and by interests. Having a strong character is, for me, being able to withstand anything that comes along your way and you know how to deal with it head on.
In case of confidence matters, its how the person moves, walks, and perceives himself or herself to other people tell really much how much confidence the person has. Its not really the clothes that a person wears, but how he handles and project himself to other people that matters. Just be yourself and know that you are a beautifully unique person will show on the outside. and smiling shows that a person is confident.
