Enlist both a hair tie and bobby pins to keep it tight. You could tie a ribbon around the low bun, but a bow with a barrette clip or scrunchie requires less effort. Fasten yours just above the bun ...

A simple velvet bow is pure Italian elegance ... keep the ends spiky to capture the look and spice up the classic bun. A chic hair pin is the ideal accent to an otherwise simple updo.
