I'm so excited I got my first Bbag today. I bought a Blueberry Parttime from AR. Of course, due to my nature I'm absolutely paranoid about authenticity. I looked at the guide on Bbags from At, but they don't have the serial numbers for the PT. It's got funky serial numbers on the inside leather tag and the tag that came with it does not say part time. But as far as the bag, its so beautiful so smooshy, thick soft , and smooth like butter.
