I think Lego hit it out of the park with Friends.
Some girls like pink and frilly, some don't. My oldest is rarely to be seen wearing anything other than black (and then it's only red and gold when she's cheering on the 9ers and obsessively updating her football blog). My youngest is rarely to be seen wearing anything other than pink and other bright flower colors.
Outside of what colors they should or shouldn't like, they both like kittens, zombies, cooking shows, gaming, my little ponies, power walking, bunnies, Doctor Who, Disneyland, Game of Thrones... Both are writers - my youngest "pink" girl writes thrillers and dark fantasy, my oldest "tomboy" girl writes light to medium-dark fantasy.
Stereotyping only gets you so far. There's nothing wrong with girls or boys who like pink bricks or don't like pink bricks.
