I have been thinking about this a lot lately and am starting to see the Birkin get a lot more mainstream exposure. It might just be something I've noticed but it seems that Birkin knock-offs are becoming more and more commonplace but than that the style of the bag as a trend. I've noticed Birkin style bags in some high-street stores and think that the shape and the bag itself will only continue to grow in popularity with the mainstream. Anybody else's thoughts?
