I have that bag and the same problem, I was warned by the sales assistant that the leather as it's lambskin would slouch lots with use, so not to use as an everyday bag. The felt organisers r a great idea and I may give it a good. Glad I read this thread.
How ridiculous not being able to use a Bayswater as an every day bag. I wouldn't spend that money only for the bag to sit in the wardrobe until a 'special' occasion came about.
