Flowers or feathers?

If it were me in your situation..... i would go for neutral colour in the flowers, like ivory or white to match your dress (which im asuming is either ivory or white??) you can get silver beads and wire put thru the flowers (this is what im having) which could be likened to stars as they sparkle and glitter and the silver thing ties in with your scheme. Another option would be to use silk flowers? they come in every imaginable colour although will be slightly more expensive than fresh if you want them to look really professional and real. Feathers can be found in dark blue so you could have them in the ivory or white flowers to add some colour. I would try ebay or similar for those and just give them to your florist to put in the bunches. Hope this helps a little! good luck and best wishes for the big day!
