I am selling a set of two long-sleeved Suit Select undershirts (navy and gray). These are thin, perfect for spring and autumn, and made of 100% polyester, making them lightweight, breathable, and comfortable to wear. The size is recommended for those with a chest measurement of 88-96cm. These undershirts are from Suit Select's "RBC (Relax Basic Cut)" line, featuring a silhouette that is neither too slim nor too classic, with a moderate amount of room. Designed for both ease of movement and comfort, they are suitable for business settings as well as casual wear. The navy color gives a calm impression, while the gray has a soft and elegant atmosphere. Both are easy to match with suits and jackets, offering excellent versatility. They are also resistant to shape distortion even after washing, making them ideal for everyday use. The condition is good, with no noticeable stains or damage. Highly recommended for those looking for comfortable undershirts for the upcoming season. Immediate purchase is welcome, first come, first served!
