Yeah, I just don't like the concept of black cap toe derbies. Black is the most formal colour for shoes, so they're a little in between everything, a mix of formalities. It's a little like a tweed navy pinstripe suit. Brown cap toe derbies are fine though. Anyway, I was advising him he might as well go for oxfords the next time he's looking to buy shoes. Seen as Rudals didn't know the difference between derbies and oxfords, I thought it would be helpful if he at least know what it is.
Now that I'm thinking about it, I might have a negative view of them because people who wear ill fitting polyester suits with terrible ties also tend to wear black cap toe derbies around here, while people in very nice suits and ties tend to wear black cap toe oxfords. It's almost like a class divider. Kinda weird, because oxfords don't cost more than derbies.
