Babylone vs. Cabas Mezzo? Which one is a more "classic iconic piece that will withstand time" (like Audrey Hepburn's Speedy or the Alma)? (I ruled out the Batignolles and Bucket because they don't have zippers.) Is the Cabas Mezzo too casual for professional/work use? Are the Babylone straps too long? Which one will be around in 30 years? Which one looks better? Overall, what are your opinions on the Babylone and the Cabas Mezzo?
