501s
Yeah, on my old pair, the top button of the fly tends to come undone easily. In the olden days, that sent a message in the bars that I wouldn't necessarily want to convey out among the general public today.
I found a pair for my husband Dave at a thrift store up in gold country earlier this year, and I have a feeling the staff at his assisted living facility doesn't care much for the button fly system. My buddy found a jacket but later felt it was too big for him, so I have it now. He and I are heading up to that same area perhaps next week, so I'm hoping to hit thrift stores there again and will be on the lookout for 501s that fit me.
New ones would take forever to fade since I wear them so seldom. There used to be a product that I think was called "Soft 'n' Fade" that would work with one washing. I'll have to see if it or something similar is available, then decide if spending $50 or whatever it is now on a pair of new 501s even makes sense.
