Editor's note: The hairpin is truly the princess of hair accessories. It doesn’t have to do the work of corralling or holding up the hair. It doesn’t have to keep your extensions in place or help you stay cool on a hot summer day by keeping your hair off your neck. It’s simply there to be admired, to add a little accent to your already-lovely hair. Start by admiring the hairpin in its many varieties as shown in this beautiful collection, and then get yourself a sweet Hairpin wallpaper!
