You can go to a black tie event and wear a good old fashioned bow tie. Or you can go and wear a Batman bow tie. Why not be the life of that stuffy old party, and let some of your personality show through? At $5 a pop, these leather clip-on ties are meant to be hair accessories but can also be worn around your neck. They’re 3 inches in length, and are secured with a 4.5 cm alligator clip in the back.
