I know this jean jacket is over 25 years old. My daughter is 22 and I owned this jacket several years before I gave birth to her. it may even be 30+years old. I only wore it a handful of times but kept it for sentimental reasons- I'm ready to let go now. it is in excellent shape for its age, but as you can see there is some slight discoloration around the neck band. I have never washed this jacket and I'm pretty sure the discoloration will go away if you get it dry cleaned, but there is no guarantee. The tag states machine wash, but I was afraid to wash it. the tag states that it is a size medium but I remember usually wearing a large in all my clothes when I got it, and it fit me just fine. I think it would work for a medium or a large size. The sleeves are generously long for biking.
