Wow --- your Neo Cabby sure was a workhorse the last six months! It has really served you well! It must still look fantastic though!
If I had favored one bag for six months over the others, I think I would feel bad that I neglected all my other purses --- lol --- since I usually try to rotate on a daily basis or at least every 2-3 days. The most time I used for one bag, the bordeaux Mirage Speedy, was two weeks, after which time I felt I had to give this baby a rest.
