We got some very plain flowergirl dresses, that had a plain jacket with them, and decided to do them up to match our colours.
I took the plain jacket, and added some ribbon in our colour. I hotglued them in place, then stitched them as well.
I took the plain dress, and added a blue bow, which tied in the back, and some blue tulle underneath, that you could see when they walked. The girls looked beautiful.
