I know how oxymoronic that sounds but it is possible. Spring and Summer are not only more open to louder colors but they’re also more forgiving when it comes to perceived relaxation of formality. A great way to accomplish both is to swap out your metal cuff links for some knotted fabric ones. You can usually find these in packs of three at department stores and they come in a variety of colors.
There won’t be anything in-your-face about these and that’s great. Good style is all about the details.
