The last thing anyone would expect is for fiber optics add class to an outfit, but designer Francesca Castagnacci has turned this fashion flub into a sexy and sophisticated statement on energy efficiency. Taking an of-the-moment stiletto of her own design, Castagnacci wrapped it in fabric woven with earth friendly LEDs and light-reflecting optical fibers and created a stunning piece perfect for a night on the town! An impressive exhibit of craftsmanship and creativity – and certainly an attention grabber – we wouldn’t be surprised if Kate Perry were to slip these babies on for her next red carpet walk!
