The devil is in the details. This is especially true with fashion. As loafers become more common this spring and summer, add a penny to your loafers, that is why they have the name.
It adds a bit of unique flair and style to the classic shoe, plus it can be a nice conversation piece and certainly will ensure you don't look like everyone else.
Just make sure that the penny is from 1982 or earlier, so that it is a true bronze penny and not a metal conglomeration.
Here are my JCrew loafers with pennies Lincoln side up.
