I am an investment banker in London and I an most of my colleaques would dissagree with that... elegant loafers are ideal....just against loafers for important interviews and business. I sometimes wear loafers with a suit, but not with a conservative business suit. Some can look better than square-toed shoes with thick rubber soles. A sleek Italian loafer with a thin leather sole will look much better than a bit loafer with shiny yellow brass. But I would never wear loafers to a job interview, especially at a bank.
I thought the only thing standard in political circles was infidelity.
square toes, or thick rubber soles would ensure load to a riot on the trading floor... might be fun though!!!
