Revelry tulle champagne bridesmaids dress!!

I have this bridesmaids dress from revelry. Tags are still on and it has never been worn. It is a size 10. I have to change dresses due to this dress being huge on me! I have the color champagne. I have attached pictures of what the dress will look like fitted when the one of me trying it on. It is a beautiful dress just way to big for me and alterations are to expensive!!
