The size is 170. (I selected 160 because there was no 170 option in the kids' section.) I wore these for two years, in spring and autumn. In the first year, the waist was too big, so I took it in. In the second year, I let it out. (Waist has been altered). There are adjustable elastic waistbands, so you can make it bigger or smaller. There is a small scratch on the front of the left thigh (see photo), but I think it's hardly noticeable. I wrote my name on the tag, so I erased it with a marker (see photo). There is some wear and tear, but I think they can still be worn. I am selling them because they are too small. I will compress them for shipping. I do not have any pets. I am a non-smoker. Please ask if you have any questions.
