Message: Hey, i have been wondering how to die pants. I'm not thinking of tie-dye pants but dying pants to look as if they were those really "cool" ones that cost over one hundred dollars. I would be great if you could help me out with this. Thankyou.
P.S. If you need a picture of what kind of pants I am talking about here is a link you might be able to go to.((highlight and paste into browser search bar))

It would also be very cool if you might tell me, if you know of course, how to make those little lines on the upper thigh part of the jeans.
Thankyou for your time. = )

This style is not the result of dyeing; it is the result of abrasion.

Normally, indigo-dyed denim has dye only on the outermost layers of each fiber. A little wear removes the color, leaving lighter regions. It used to be that one had to actually wear jeans in order to make them look worn, but now manufacturers mimic the effect of aging by washing the garments with abrasives, or possibly with cotton-degrading enzymes.

Perhaps the simplest way for you to copy the effect, without going to the trouble of wearing the jeans for a long time yourself, would be to rough them up with sandpaper, perhaps while you are wearing them so as to make sure that the right areas get the wear. (I do not know of a source for cellulase enzyme.)

The light lines are the results of folds in the fabric during the abrasion process. Wherever the fabric is folded, the fiber that sticks out the most will receive the most wear.
