Brown is a criminally underutilized color in classic menswear, but by combining it with easy-to-harmonize bright blue in this pocket square, you will have no difficulty integrating this beautiful earth tone into your looks. The brown provides a subtle grounding effect, both toning down and emphasizing brighter shades like the light blue itself.

While this color combination is ideally suited to transitional and warm or hot-weather seasonality, with the right pieces, it could also be worn year-round. While not suitable for the most formal dress codes, it will function well in a wide swath of formalities, including business attire.  

The crisp white linen provides a clean and classic backdrop, while the brown and bright blue X-stitch detailing offers a subtle yet striking contrast. To combine this pocket square with outfits, pair it with a navy or brown suit and a white dress shirt. The brown and bright blue stitching complements these suit colors, creating a cohesive and polished look suitable for both formal and semi-formal occasions.
