Size S. I always wear size S. For spring and summer. No lining. It reaches about the ankles on me (155cm tall). I bought these for business, but I have several beige pants and have only worn these twice. I'm selling them because my job has changed. These are neat pants with a center line. The condition is good, but if you look closely, there is a faint ballpoint pen mark on the left knee. It's barely noticeable unless you look closely. Please check the last image. There is also some slight blackening near the ankles, but you'd have to look closely to notice it.
