Great thread!
This is actually one of my New Years resolutions as I've found myself doing this since I've had my baby over a year and a half ago. I use to rotate my bags daily and now I use the same bag almost everyday. Meanwhile I have a closet full of gorgeous expensive bags just sitting there. So I've decided in 2016 I will use and enjoy my nice bags more often since what's the point of having them otherwise, and I will let go of the ones that no longer fit my lifestyle or I'm not absolutely crazy in love with.
