Weddings. Graduations. Office parties. Whenever you've got cause to break out your suit and celebrate, these on-point pieces will make sure you nail the details. The pocket square from DIBI is foolproof, thanks to the subtle, simple, sand-colored design in a handsome cotton blend. Use it to anchor a bold shirt/tie combo, or let it provide some subtle contrast if you're wearing a dark, simple number. The cufflinks from Urban Professor are made from brass that's plated with shiny white steel, styled after traditional silk knots, and ready to fasten your French cuffs with old-school class.
