Hi Ted,
In today's world the norm is to have "white" buttons on one's PC-- white meaning "silver coloured"; real silver buttons are the exception these days, and I seriously doubt that even one-in-one thousand gentlemen actually sport sterling buttons on their PC or doublet.

If you don't like the "shiny chrome" look you have a wide range of options, starting with the black plastic buttons (like those found on suits), fabric covered buttons, glass, jett or pewer buttons. Shapes can be square, round, oval... whatever strikes your fancy. It is all a matter of style-- or some might say eccentricity!

As long as you like your buttons-- they are "socially" correct.
