Next pair

I decided to send one of my old jeans for repair. As my fishing tackle, I have several new backups, but some are getting up close to so called 'vintage' or 'old fashioned', so I'm a little hesitating to wear them. Now, I'm wondering if I should start wearing this pair (dead stock Lee 202, presumably made in the 1970-1980s) or I should buy a new one.
