If your looking for inexpensive and unique boutineers, check out Twisted Crystals on Etsy.com I was searching for an alternative to a flower boutineer when I found Twisted Crystals. I had my shoe clips made, which match the groom's boutineer. In addition she made the groomsmen boutnieers, and my fascinator. Each piece is custom made to my specifications.
