I entered "M" but the correct size is unknown. The waist size seems to be 67 as indicated. Near new condition - no noticeable scratches or stains. Thank you for your interest in this product. To prevent any issues, I've included the following information. I judge that there are no major defects and I am listing items that are relatively clean. "No noticeable scratches or stains: There are scratches or stains that are only noticeable upon close inspection." That's what it means. How much close inspection is needed to notice something varies from person to person, but in my subjective opinion: Pilling, fuzzing, unraveling threads less than 3 cm, stains less than 5 mm (or not limited to 5 mm if the stain is light), tears less than 3 mm (excluding the knee area of pants), fading, wrinkles Even items with the above issues, or items without such issues, may be listed as "no noticeable scratches or stains." If you are concerned about these things, please consult with me in the comments before purchasing. In that case, I will increase the number of product images and will carefully check any areas of concern if you inquire. I hope we can have a smooth and pleasant transaction, so thank you for your understanding.
