You know, I have a pink trigger that I know to be authentic (bought at dept store) that looks almost exactly like that. It's from about 3 or 4 years ago. It doesn't have the botkier print in the lining either and the lining is similar to this one. The nameplate is also in the same place. So this one could be authentic, but just an older model.
on the other hand, I agree that the zipper pull looks weird.
So I think emailing botkier is a good idea.
