This is a brilliant fashion concept that should have been obvious, but it took the inspired mind of Dulce Calaveritas to develop it. She makes a wide variety of geeky bow ties. Her Batman ties are, though, the best.
Clearly the next step is to develop a functional, razor-sharp steel batarang that also serves as bow tie. Then, even in formal wear, Bruce Wayne remains in uniform.
These ties are leather, but she also makes vinyl versions.
