Yes it works and it’s easy to do.

i’ve dyed clothing black and it’s quite easy to do. The only problem is that if you don’t set the colour it has a tendency to wash out again.

I imagine it would work, but you’d need to be careful about getting it even. Have you considered contacting the shop/ manufacturer and complaining?

Yes years ago i put bleach on denim jeans and made a skirt and a pair of jeans.

The navy blue part is just weird, makes me think they were of not good quality and not a reputable business and I’d be taking them back or at least writing to complain and name and shame them.

agreed with most here, definitely return them, this should’ve have happened when they are somewhat newish still.

I would be taking them to a professional! I guarantee if I tried anything like that I would end up dyeing most of my wardrobe!

Personally, I’d return them to where I bought them from, as that just shouldn’t happen. But if you want to dye them, and you don’t feel confident doing it yourself, take the jeans to a good dry-cleaner, as most of them will dye cloths for you.

I’d return them rather than try fix them. If it doesn’t work evenly you won’t then be able to return them.

You can get some specific denim dye.. Go to a fabric shop and ask the people there

I’d be taking them back or writing to the company – it shouldn’t happen. Even if you’ve washed them more than once and don’t have a receipt – still get in contact with them.

My daughter has used the dylon dye that you put in thew washing machine and her outfits have always come out looking fantastic but shes never dyed Denim.

I haven’t dyed clothes for years, not sure how denim would go though.

I have used Dylon in the past which was great to just chuck into the wash. Don’t know how well it would go in a front loader. I don’t think there’d be a problem after all you are dyeing them black but I agree be careful of too many creases.

I think you can but it may take a couple of goes to get them as black as before

I’ve never tried to dye jeans, but I imagine it would work – you’d have to be careful not to have creases in the clothes while dyeing them, though, or the color will be uneven.

I’ve not dyed jeans before but I think I’d be taking them back if they couldn’t withstand a wash without fading, and it’s odd they faded to blue, rather than a dark grey.

Depends on the amount of nylon or non Cotton additive.if they were pure cotton they’d go jet black with Dylon dye which is great by the way.
I dyed a pair of maroon jeans and they went very dark a good colour but not black; hence they had more nylon in them

Dylon sell a colour remover product which is great. I accidently put my son’s pale blue blankie through the wash with a red sheet. He wasn’t happy blankie was now pink. I got the colour remover at Spotlight and blankie is now pale blue again.
