What is this wedding dress?

This was my grandmas wedding dress she got married in the 80s or 90s I’m not too sure, but this was her gorgeous dress. She gave it to me for when I get married when I’m older. I’m obsessed with it and I wanna know more about it! She said it was some sorta Italian designer special in 1985 or 1995. Can anyone help me find out more about it?
