Just a counter to the "fake goyard guide".  I have visited the store in Paris multiple times.  I have in my possession, bags with both matching and white/cream colored stitching on the trim.  It depends on the style.  You may have purchased a real GM or PM sack that has white/cream stitching on the trim and handles so don't worry.  The comment was correct about other knock-off problems.  However, there is really nothing horrible about purchasing  a knock-off as long as you don't pay as if it is real.  Be careful and have fun!

If you want to compare the bag you are looking at to an authentic, go to the Barney's website.  Note that the authentic bags have snaps which match the color of the bag.  I have never seen an authentic bag with a silver or gold snap.
