Copper/dark Rose Gold Bridesmaid Dress help

I have been searching high and low for copper bridesmaid dresses with no luck. I'm hoping for something affordable for the girls also. I love the shiny dresses and I've looked at rose gold but a lot of those seem really light in color. Any suggestions on where I can look? Or what other colors I can search that might be close? My other main color is navy, and accent colors are dusty blue and dusty pink.
