I've noticed that even my branded leather handbags deteriorate
after a while, to the extent that they 'jian4 bu4 de2 guang1'
(can't be used anymore without embarrassing me!
).
So, now, I prefer to have just one or two branded ones for special
occasions, and for everyday use, any bag that catches my fancy will
do!
As long as they suit the purpose and function, and
matches with my outfit, I'm happy-to-go! 
What to do... got limited income and my 'priority purchases' every
month would be books, mags and CD's, and oooh... costume jewellery
and trinkets... so, too bad, handbags and all else shall have to
take a backseat!
