70s Style Wedding!

Hey guys, I need help! I'm planning a 70s wedding and mostly doing it on my own. I was born in the 90s and my fiance was born in the 70s so I'm a tad confused on how I really want to pull this off. What colors would you suggest for this type theme? I'm not looking for the traditional white or ivory colors (including the dress) so I want to do this all different. I'm thinking of a blue for the bridesmaids but what color should I go with? Gold, maybe? I'm not sure I'd like the gold idea. I tried on a gorgeous navy blue ball gown with gold lace and it was perfect but not for my type of style. I plan to do a mermaid type dress with cap sleeves and possible long sleeves. I'm gonna have a bohemian styled dress for my reception. Just throw any ideas you can at me please? I plan to make most or all of my decorations, bouquets, etc!
