We’re guessing Madonna doesn’t do bake sales or field trips, but one thing the material mom does do? Fashion! To help daughter Lourdes with a fundraiser at her school, New York’s LaGuardia High School of Music & Art and Performing Arts, Madonna donated a signed pair of thigh-high black-and-white Chanel boots, available for auction now. The snap-up shoes, a European size 38, feature the iconic Chanel logo on the heel and nary a scuff on the sole. The minimum bid for the boots is $1,000 — no takers yet! — and they’ll be up on the LaGuardia website through May 12. Other items at the annual auction include tickets to New York City Fashion Week, fabulous beach getaways and more.
