If you want to wear cufflinks with a blue shirt to work, you should do so carefully. As coloured cufflinks can easily clash or appear overly bold with a blue shirt, it’s best to keep things a little conservative. To do so, try playing it safe with a pair of silver cufflinks.
Doing so will allow you to play with different shapes and designs without appearing inappropriately dressed. Alternatively, if you do want to wear a coloured pair, try opting for cufflinks in a shade of blue that contrasts your shirt. For instance, if your shirt is light blue, add dark blue cufflinks, and vice versa. This will keep your appearance consistent and smart without allowing it to look overly monotonous.
