There are three sorts of people who wear bowties:
1) People who can pull them off.
2) People who can't pull them off, but wear them anyways.
3) Old people who can get away with it.
The first is a rarity, the second and third are the most common, with only the first and third ones being excusable.
Furthermore, there are two sorts of people who fall into the second category:
A) Losers from Reddit who have masturbatory-esque feelings for the 1950s. and wear bowties with their "World's Worst Fitting Suit™" and their "fedoras" (Which, most of the time, are actually trilbys.). and square-toed loafers
B) Whovians who think that wearing a bowtie makes them as cool as the Doctor (It doesn't.)
