Everything in weddings these days are no longer conventional, even the bouquets. A friend of sister had such a wedding and commissioned my sister to make bouquets for the bride's maids. So sister made her origami spring iris flowers and made bouquets out of them. She also made mini bouquets for the flower girls, but unfortunately she was not able to take its pictures.
These bouquets won't wilt and can be stored in a cool dry place, away from the sunlight to preserve the color of the paper. These bouquets also don't put a dent to your budget, if you know where to look for it, or if you can find somebody to make it for you.
