Boutanniers/Corsages

Hello,
We had selected Fressia`s as the flower to use in our boutanniers and corsages, but I just found out that my step-mom is allergic to Freesia`s. (Go figure, the only flower she is allergic to we picked that one!). Anyway, having a tough time thinking of other nice flower arrangements for the bouts and corsages. My bouquet and all the BM`s are Gerbera Daisies. Any suggestions? I was hoping not to use roses or carnations.
