Patterns of fading in jeans

I started to research about jeans, and the first thing I decided to look at is the patterns of fading in jeans. 

Patterns of fading in jeans are caused by continuously wearing them without washing, which became the special of dry denim. 

These are the specific names of the patterns:

Honeycombs----- These are faded lines that are found behind the knees.

Whiskers----- Faded streaks that surround the crotch area of the jeans.

Stacks----- These are created by having the inseam of the jeans hemmed a few inches longer than the actual leg length.
