Pink is such a great color, but it gets a bad rap for being "girly" or "feminine," which I don't understand at all!
Pink
Pink is a pale red color that is named after a flower of the same name. It was first used as a color name in the late 17th century. According to surveys in Europe and the United States, pink is the color most often associated with charm, politeness, sensitivity, tenderness, sweetness, childhood, femininity and the romantic. A combination of pink and white is associated with chastity and innocence, whereas a combination of pink and black links to eroticism and seduction. 
Etymology and definitions.
Girly girl
Girly girl is a term for a girl or woman who chooses to dress and behave in an especially feminine style, such as wearing pink, using make-up, using perfume, dressing in skirts, dresses and blouses, and talking about relationships and other activities which are associated with the traditional gender role of a girl.
Though the term is sometimes used as a term of disdain, it can also be used in a more positive way, particularly when exploring one of a range of gender positions.
