Would you guys recommend doing fresh floral for all the decorations or for just the Boutonnière's and Bouquet? We're not having a tons of flowers, mainly just like sage green and forest green vines and leaves.

What are some good dresses that won't break the bank? Also, would you ladies recommend the Bridesmaids paying for their dresses or the Bride and Groom? I only have 3 girls!
