Here is photographic evidence...
A classic pair of denim chinos. Not apparent from this shot is the pleated nature of these pants. Also notice the all-white sneakers -- a classic accompaniment of the denim chino. Fortunately, these were not waistband denim trousers. Still, I felt sick to my stomach and had to go stand outside.
When this "man" left the post office, he stood outside, directly facing me for a minute, and I pulled out my phone and quickly zoomed in on his atrocious "pants" to take another picture. In a cruel twist of fate, my memory was full and therefore I only had time to quickly grab a shot as he was walking away. Honestly, maybe that was for the best, because these pants were overwhelmingly bad.
