Black Shirt

What can I use to dye a faded black shirt back to its dark black color?
I have this black halter top that has faded somewhat that I don’t want to get rid of. I actually love the shirt and I want to wear it this summer. What products can I use to dye the shirt back to it’s dark black color?
Rit dye works pretty good. You can find it most department or grocery stores.
