This dark blue checkered shirt with an Oxford structure has a Button Down collar which is considered to be the most common collar for sports and casual shirts. The tips of the collar are fastened with a button, which keeps them in one place. The collar looks just as good with or without a tie. The Oxford structure gives the fabric lightness and breathability, so you can wear the shirt even in summer under a lighter jacket or suit. Oxford is a type of fabric weaving, where different colors and different strengths, for example double, yarns are used in the warp and weft. The result is a structured shirt that is breathable, strong and durable. Used for less formal shirts and classic polo shirts. The 100% cotton material is from the luxury Italian manufacturer Monti. Real mother-of-pearl buttons made from seashells are a beautiful accessory.
