There’s nothing wrong with pink. It’s a perfectly fine color. The problem is its arbitrary association with gender, to the point where it becomes a code for what girls and boys are “supposed to” like and dislike, and prevents them from judging for themselves what they like based on any dimension other than color.
Nor would I necessarily take issue with princess fantasies, on the grounds that fantasizing oneself as royalty, a dragon-slayer, or a time-traveler can all be healthy exercises in one’s imagination. The deeper problem is that wanting to be a princess is too often about wanting to be pretty, pampered, and protected. To the extent that it’s about something in one’s control, becoming a princess is about being able to marry a prince. I’m not too keen on encouraging young girls to define themselves or build dreams around their marriage prospects. I think the key question to ask girls playing at being princesses is, “What will you do when you’re a princess?”
What does a girl do when she’s a pretty pink princess? What does she do to become one?
Peggy Orenstein and others have dissected the dangers of wanting to be pretty along the lines of promoting consumerism, narcissism, eating disorders, and premature sexualization of girls. At its simplest, I see the ideal of “being valued for what you do and not how you look” as just another expression of the importance of believing that effort and controllable behaviors matter more than intelligence, talent, or looks. I won’t dispute the value of attractiveness or positive self-presentation in influencing success or self-esteem; the issue is that improving one’s appearance is more limited in capacity than improving one’s skills and ultimately more limited in impact. One can only be so average (noting that more average faces are more beautiful), but one can always be more capable.
I also worry about encouraging children to seek some status or reward simply for its own sake. The pleasures of being pretty go beyond ornamenting someone else’s world and receiving an extra boost in attention. Attractiveness shouldn’t be an end in itself, but a stepping-stone toward further positive outcomes—whether building confidence to pursue ambitious goals, landing a CEO or political position where leadership can make a difference, or developing interpersonal skills that help bring others together. Otherwise it’s little more than an uncashed lottery ticket, devoid of real appreciation.
For me, the bottom line is about helping all children to pursue goals which they can control and which will help them develop. I want them to choose games and activities based on how interesting or worthwhile they seem, not some marketing message that arbitrarily dictates preferences around colors and images. I want them to actively create their own questions and ambitions, explore the world, and forge paths toward fulfilling those desires. I want them to focus on boosting what they know and can do, not what they have and how they look, to better support them in tackling future challenges.
So the next time I see your daughter, please understand if I don’t immediately comment on her adorable outfit. I’m probably debating whether to reinforce her perspective-taking, self-regulation, or cognitive flexibility.

 There’s a phrase (I thought) I once heard, about the unrealistic yet persistent modern belief in “the infinite perfectibility of the human body” and its application to girls’ striving to be thin and beautiful. Unfortunately I haven’t been able to track it down; if you know its source, please send it along!
 I’m not interested in pandering to stereotype with boy-targeted car imagery or girl-targeted pink frills, whether for “good causes” or for some toy company’s profit. Even if topics like online shopping and cosmetic surgery interest more girls in statistics, I would still advocate finding more neutral problem contexts and framing for both boys and girls.
