Who would have thought that the sk8er boi girl would sport a real cute bag? Is Avril Lavigne all grown up and leaving her punk roots to become a fashionista? Nahh. But she has opted to wear a trendy bag. Avril Lavigne was spotted wearing the Kooba Sienna Bag. The Sienna is perfectly fitting for this punk girl, it has chunky handles and detailing and studs. I always kind of liked Avril and now I do a little more. If you love the Kooba Sienna buy it through eLuxury.
