I've been doing a research into men's Victorian fashion lately because of book cover designs. I uncovered a wide variety of collar and neckwear styles--they range from cravats to bow ties. Vests--I should say waistcoats since we're talking British--were commonplace among upper and lower classes alike.
I've just started writing a new story too, where bow ties feature. So I give you this fine Victorian gentleman with s bow tie and beautiful mustache.
