This is a Brooks Brothers long-sleeved shirt. The material is 100% cotton. I purchased this as a used item, and the previous owner had adjusted the width. There are some traces of this alteration. Also, there are some damages in several places. I have included photos as much as possible, so please check them before considering a purchase. The fabric is crisp, and there is no yellowing around the collar or cuffs. Size Marked 17-4/5 (REGULAR FIT) Actual Measurements Length: 85.5 cm Width: 67 cm Shoulder width: 52 cm Sleeve length: 63.5 cm Pattern: Solid Collar Design: Regular collar Material: Cotton Color: Blue 164
