Some of us would like to search for bowties that look like actual bowties, rather than giant bows with tails. The bow in post #5264737 is not a bowtie, but good luck educating legions of taggers to stop using the tag that way.
It is a bowtie.
Even if you apply the very narrow definition, it is still worn just like one.
It just looks fancier, because in anime art, everything needs embellishment.
