They are older styles and they are used. Her bags look fine to me, but what do I know.
I believe there was no change in classic style. Quality, yes. But no change in style.
Classic style is easiest to spot for fake because it's hard to make and whatever been made few years ago continue until this day. I am talking about classic flap which is the flap with leather interwoven double chain, quilting and CC lock.
Keiko who works for Chanel boutique more than 10 years told me the maroon color for interior lining on lambskin classic flap is a classic color and has never changed.
Fake lambskin classic has red but not this maroon red.
I never regret paying 2K for that classic red color.
