This is a long-sleeved shirt from THE SUIT COMPANY (スーツカンパニー). It's an easy-care shirt, making ironing a breeze. The plain white shirt is size 38/80. The white shirt with a floral lining is size S. The S size is slightly smaller, but the difference in size is minimal. This is a set of two shirts. I'm selling these because my work attire has become more casual, and I rarely wear them anymore. They are in excellent condition with no damage or stains, but they are pre-owned and have been stored at home. I appreciate your understanding. Please refrain from purchasing if you are overly sensitive to imperfections or expect a perfect item.
