A man wearing headphones and a checkered shirt with tan jacket reaches inside his jacket while crossing a busy street.
The man is wearing jeans.
The first sentence does not tell us what kind of pants the man is wearing.  While it is safe to assume that he is wearing pants, since it would be very unusual to see a man crossing the street without them, we do not know if he is wearing jeans.
