We love Repetto for their comfy, pretty, and very Parisian ballet flats and lace-ups, which we stash in our bag for quick shoe changes when heels get too treacherous. But this new collaboration with Karl Lagerfeld, shown on his spring '09 runway, really takes the brand to a whole new level. Both the flat and the heel version come in black or white patent leather, and feature a removable patent leather "tutu" that looks kind of like a tiny lampshade for your feet. We wonder how much the shoes will cost, given that most Repetto flats go for around $300. Guess we'll find out April 9th, when the shoes go on sale at colette. Just the thing we needed to round out our under $200 sundresses! (Nitrolicious)
