This was clipped from InStyle back in 2006! For some reason, details are provided about the dress, but not the bag. What is the logo? I tried to blow it up as much as possible...Is it a sailboat? A woman??
I'm sorry, I don't know very much about Lanvin bags, I just know the details enough to spot one. You might try to ask a more specific question in a new thread in the main handbags forum like : "What is the name of this Lanvin bag?" and hopefully a Lanvin expert will help you further.
