You can favorite outfits. You can mark items as borrowed (so you can remember that you loaned your favorite bag to your neighbor). You can mark them as dirty or at the dry cleaner, needs repair, and if you no longer own something throw it in the trash.
Closet Service also makes packing for trips easer with the "Suitcase" feature. Suitcase allows you to plan your outfits weeks or even months in advance.
