This summery collar features a cerulean blue top strap layered over a hot pink base strap and purple liner, with white stitching and nickel plated plated brass hardware. The collar is adjustable from 15 to 18 inches, and is 2" wide. It is cut, tooled, dyed, stitched, and assembled entirely by hand. To measure your neck size: Measure the base of your neck using a soft measuring tape or string, then round up to the next half inch. The tape should be snug around your neck, but not tight.
