White %100 polyester bridal dress

Hi!! I bought this dress today, second hand today. It’s bridal and 100% polyester. It’s got a lot of different fabrics from mesh to silk. I want to see if I can dye it a dark green? I love the white but it’s not practical as I want to wear it to a ren fair.

Any advice would be amazing, I’m going to do some further research today.
