Any ideas on how to decorate a three tier princess cake with edible flowers?

and where do i find them i would like real edible flowers i will be baking the cake myself. I have an original disney cinderella doll ( like barbie) to which i made a dress out of textle but dont know how to attach it to top of cake and would like to obtain some help on this i have no experience on this subject and dont know where or how to make or find already made decorations.
thanks for your help.

THERE ARE SEVERAL WEBSITES THAT GIVE THE NAMES OF EDIBLE FLOWERS. MOST FLORIST CAN ASSIST YOU WITH THIS, ALSO. I SUGGEST DIPPING THE FLOWERS IN GRANULATED SUGAR FIRST. I DIPPED THE ONES ON MY DAUGHTERS CAKE IN A MIXTURE OF POWDERED SUGAR AND WATER WITH JUST A TINT OF FOOD COLORING, THE SAME COLOR AS THE FLOWER. POWDERED SUGAR ALONE CAN LIGHTEN THE COLOR OF THE FLOWERS. I ALSO PLACES WHOLE STRAWBERRIES, BLUEBERRIES, AND CHERRIES BETWEEN THE FLOWERS ON MY DAUGHTERS CAKE. I ALSO SLICED A BOWL OF THE FRUIT THE NIGHT BEFORE, AND ADDED A SMALL AMOUT OF SUGAR TOO MAKE A SYRUP. WE SPOONED THE FRUIT AND WHIPPED TOPPING OVER THE CAKE. I HAD 25 CHILDREN ATTENDING, AND NOT ONE OF THEM COMPLAINED. IF YOUR CAKE IS GOING TO BE TIERED YOU MIGHT PLACE THE DOLL ON THE EDGE OF ONE OF THE TIER, FACING THE CAKE, ARMS OUTSTRECHED (USE THE OUTSTRECHED ARMS TO PROP HER AGAINST THE NEXT TIER OF THE CAKE) AND ONE LEG BENT BACK, TOO GIVE HER THE APPERAENCE OF RUNNING. THEN PLACE ONE OF HER SLIPPERS ON THE TIER NEXT TO HER FOOT, APPERARIN AS THOUGH SHE LOST IT. HOPE THIS HELPS.
