I have to say, the 2017/2018 wedding season is my fave so far (after 14 years of doing wedding cakes!)
Bridalguide.com sums it up:
Rustic – This one is now on it’s 3rd year, the most popular for Bella’s Desserts
Whimsical – My personal favorite
Over the top – Seems like this has been around for at least 40 years!
