J Crew Authentic Men's Navy Blue and White Striped Polo Shirt Large Stretch Pique Knit Goods. Shirt is pre-owned. but doesn't look worn much if at all based on condition. Please see all photos for visible condition. In some lights, it looks black but when taken outside in natural light I believe this is a dark navy blue. Left pocket on front chest. 98% cotton 2% elastane. Approximately 26 inches long x 22.5-23 inches pit to pit. Very nice collared casual shirt!
