Good morning! Yes, Dala fabric dye would be a great option for dyeing denim. Dala dye is specifically made for fabric and comes in a variety of colors like olive, purple, black and turquoise. At only R24.99 per 30g bottle, it's also very affordable. I'd recommend trying the olive or black Dala dye for a natural looking dye job on your jeans. Let me know if you have any other questions!
