For many years, I have been a fan of dyeing clothes. I think my dyeing days started years ago when I wanted a pair of solid black jeans. With my statistically extreme 'out-in-out' figure, I have always struggled to find jeans that (a) have a high enough rise, (b) fit me in the waist and don't gape at the back, (c) fit me in the leg, and (d) are a shape/style that I want. But jeans are a whole other post, so I'll stop there with that topic.
Suffice to say that I found it difficult to get a pair of jeans that met all my requirements AND came in a colour other than 'stonewash'. So, not to be defeated, I would buy several pairs of these jeans and use dye to make them different colours. Of course with dyeing you can't get the distressed effect that was sooooo trendy several years ago but at least this gave me options as to the colours I wore on my bottom half.
