Activity for Cheryl

Does anyone have advice on where to get silk flowers? The main flower I'm looking for is very light colored peonies (which have been very difficult to fun fake... that also look nice/ realistic). Any ideas?

I'm getting married June 16th, been dress shopping twice, and haven't even been close to finding the dress I want! I just want something simple and flowy with cap sleeves and boo luck anywhere! Any suggestions?
