I just bought the Lindsey and the dust bag fit fine. my large carly came with a much bigger dust bag though. go figure. guess they give you a larger one for your carly since it's tall, and the lindsey is not.
I recently tried putting my Lindsay in it's dustbag, only to find it was a tight fit and I couldn't even pull the drawstrings closed over the top. I thought maybe the wrong dustbag was put in by accident(it was an outlet purchase). I emailed Coach, and told them that my Gigi's bag was a much better fit. They said they would send me a new one, and when it arrived(quickly I might add!) it was the same size as the one that it came with. Did all Lindsay's have improper sized dustbags?
