IMHO, one of the best compliments I ever got was from a man who told me I might be a guy, but I was the best looking girl he had seen all day.
I am a work-in-progress, never achieving perfection, but I never stop trying to achieve it. Work to achieve your best look, and confidence will follow, and that confidence will radiate out and breed yet more confidence.
I talk with women in public all the time, and they know I am a man, yet they will compliment me on my appearance or my choice of certain clothing items.
Above all, have fun being a girl! If you have a wife or a GF who is supportive, then you are blessed!
