This pocket square features a playful astronaut pattern on a deep blue background with red edging. It pairs best with classic suit colors such as navy, charcoal gray, or black, which will complement the blue tones and let the design stand out. For a coordinated look, a medium or dark blue suit works especially well. You could also try a light gray suit for a modern contrast. Avoid suits with busy patterns, as they may compete with the pocket square’s detailed design.
