Help Identifying Fabric - Working on Wedding dress

Hello,
New here! I have searched all over the internet and feel stuck. I could not find a resource online to ask that is fabric specific, so I am hoping someone here can help? I bought some fabric for my wedding dress. The only info on the bolt was that it was made in France. The employee didn't know anything. I asked a lace vendor that they said it wasn't 'lace'. I think it is polyester. I am trying to dye it a dark-ish blue color and it's been challenging. Anyone know what this fabric is called so I can try to find out fabric content online or maybe buy it in another color? Thank you in advance for any ideas!

 

Jenny have you seen our fabric resource?

You can use it to help determine the fibre, and type of fabric it is.
I agree it looks like a man made fibre from the photos and dye attempt. You may not be able to dye it :/

 

Thank you for replying.
I have tried looking it up on the resource page, but I don't even know what to call it? I looked up tulle, lace, netting, flocking...It has some kind of tulle on the back, and it's not traditional lace. I am at a loss.

 

Can you get some real close ups, of both the front, and the back and we can perhaps help you identify it.
