Disney Pixar Animation guru John Lasseter found himself tangled in a miniature fashion kerfuffle.

Toy maker Mattel Inc. had made a prototype doll of “The Princess and the Frog’s” newly minted princess, Tiana, wearing her bayou wedding dress. But one animator worried that the gown failed to reflect the one in the film, whose multiple layers resemble the petals of an unfolding waterlily.

Lasseter suggested a way to create the illusion of volume without driving up the doll’s $10 price tag — namely, printing a swirling pattern of glitter atop the diaphanous outer layer of fabric.

No detail seems to be too mundane for Lasseter, who after years focusing on Pixar is extending his reach to Walt Disney Co.’s merchandise juggernaut.
