Cufflinks don’t just serve a functional purpose; they can also be used to introduce some energy into an outfit. Use events such as a wedding to get a bit more experimental with colours and shapes.
If it’s in keeping with your style, novelty cufflinks aren’t out of the question, provided that they’re still tasteful. Labels such as Paul Smith, Tateossian and Alice Made This have some excellent examples of that manage to be both stand-out and stylish at the same time.
