It depends on which you prefer, the Diorissimo would probably be easier to maintain because it's smooth leather whereas the patent Lady Dior would be more high maintenance (can't get it wet, marks and colour stains are permanent). As averagejoe and eminere have pointed out though, the Diorissimo is currently viewable by appointment only, not sure if it's available on the boutique floor yet, because of its hefty price tag (I think another member said it was US$3800 for the small size, $4200 for the medium and $4700 for the large?), it's at a higher price range than the Lady Dior Miss Dior
