This is the MARTIN PANT by Steven Alan. I believe I purchased it over 10 years ago for around 18,000 yen. It's been sitting in my closet, so I'm selling it. It has a slim silhouette, but it's also relaxed enough to be versatile and easy to coordinate. The slanted design of the back pockets is also interesting. The size is 31. Please refer to the photos with the measuring tape for the measurements of each part. *Steven Alan is a fashion brand founded in New York in 1994.
