Dying Fashion Nova cargo jeans from blue to black using Dylon machine wash fabric dye

So I imported these Attico style denim cargo jeans from American. As I couldn’t find anything like them in the UK. When they arrived I wasn’t keen on the colour so I thought I would dye them from blue to black. I got these cargos from Fashion Nova Using Dylon machine wash fabric dye from Wilko’s I had a go at dying them. Im only little so I had to trim the bottoms. Ive got a feeling they might fray. But we’ll see how they go. The end result was quite patchy & more of a dark blue in colour but I still love them.
