Hello, I just purchased my first bbag and want to make sure it's authentic. I have been looking for the style through the number without much luck. So, any help you may be able to offer would be greatly appreciated! ID number behind leather tag inside is: 143772-2123 color: dark chocolate brown (love to know the REAL style and color names) year: maybe 2003-2004? zippers: all Lampo and look authentic from pics I have seen. Thank you for any help on the style name, year and authentication!
