This is a stretchy golf shirt made of 90% polyester and 10% spandex. The slightly thicker fabric makes it useful for the coming season. Although unworn, it has been stored for a long time, so there may be some minor folding wrinkles, but it's fine as is. It's a US size L. Flat measurements: Bust 52cm, waist approximately 50cm, length 64cm. Thank you for looking.
