I dress how I dress for myself.
However, have you seem Catch Me If You Can?
It's amazing what a good "costume" will do, and how different people will treat you.
Simply because Leonardo Dicaprio wore a pilot uniform he was able to successfully use and cash like hundreds upon hundreds of fake checks! Hilarious.

At any rate, I feel that how we present ourselves/the makeup we wear/the clothes we wear are a costume. And sometimes an old costume, though comfortable, does not fully reflect who we truly are anymore.. As we are always changing..
When I go out in sweats and no makeup men dismiss me..
When I put on makeup and put effort into my outfit (or wear a dress) they all look at me.
It's amazing actually.
