Changing dress jacket buttons

[Whidbey78]

Buttons, like cuff links, are a matter of personal taste. Gold, silver, enameled, it really doesn't matter just so long as they all match, and you are comfortable with the look.

Ditto.

Either of what you posted would be great. On a black jacket the enameled ones would make a unique touch, but might not look as good in other colors.
