If you’ve been reading any fashion blog (this one included), you’ve heard about “Material Girl,” a fast-fashion juniors collection which Madonna and her daughter, Lourdes, collaborated on.

It only seems fair that the under 2 crowd – really the only ones who should try the look if not performing in concert, now has a wider array of style options when running around in their undies.

John Paul Gaultier, who designed Madonna’s infamous cone bra and corset for the Blond Ambition Tour, recently teamed with high end Italian lingerie house La Perla for an upcoming collection under things.
