Favorite flowers: Coral peonies and cattleya orchids. I also love coral garden roses, as seen in this bouquet [which was carried by one of Oren's celebrity clients, Molly Sims, for her wedding last fall].
Best budget advice: I'd cut back on massive amounts of flowers everywhere. Use local and seasonal flowers and keep the look super minimal and tasteful. No over the top floral chuppahs! A couple of my clients got married beneath a natural chuppah of weeping willows and it was gorgeous. They stood on these beautiful Moroccan wedding blankets, surrounded by a few hurricanes filled with garden roses and ranunculus. It's important to keep it simple and let the property speak for itself.
