When I read this quote, I think about the women (and men!) who are quick to judge people by what they wear...
I think we should be open-minded to other people's version of fashion. You have to remember that style and fashion is an expression of who YOU are, not what a fashion magazine says you should be wearing.
In general, I think we should be open-minded anyway. Everyone is different and unique in their own special way. Respect other people's style and way of life and you'll find that people will be more respectful of you.
