Ideas For Bridal Bouquet

My wedding is July 1, 2006 outdoors. My very traditional, long sleeved wedding gown is a very pale mauve with gorgeous Ivory lace over it, a chapel train. My MOH is wearing a long sage green gown; my jr. Bridesmaid is wearing a butter yellow gown. I`m small, only 5 feet, 2 inches so I think an armheld bouquet would be great for me ( I like calla lily`s, orchids, roses); my MOH is only 5 feet tall, jr bridesmaid will be 12 yrs old. Can someone help me fiqure out color of flowers and types of flowers to use? I have been on line searching and can`t find "it" yet.
