You can also buy from Saks, Neimans and Bergdorf Goodman. I prefer to buy from major department stores so if I change my mind I can just bring it back to the store. Norstrom's also carries Isabella Fiore but I don't think that you can buy it online.
I beleive adasa is in Hawaii. If you buy from them make sure u want the bag and have viewed it somewhere in person bcuz i don't know what their return policy is like.
Hope that helps. Which bag are you thinking about getting??
