All the brides I talk with and help plan out their wedding day agenda, which includes the photography of course, have a pinterest page where they store ideas. I always ask to see it.
Why? I get a sense of what her tastes are. Is she a classic? or modern? Or a mix? Does she like vintage? Or new? Is she romantic or more hip and cool?
All these ideas are reflected in the details, and decor she brings to her wedding day. This helps me and also gives me opportunity for more creative wedding day photography.
A small sampling. Enjoy:
