GOOD QUESTIONS! Here are some resources for you to read and help make your decision. My husband and I had such a small wedding we did not even have a rehearsal dinner and decided to just have 1 small cake that we each got to choose the flavors for "our" layer, but since I love chocolate we actually went with a little non-traditional look and had chocolate frosting. We also probably won the messiest cake cutting award!
I wish we had this cake for our wedding since I'm originally from Massachusetts and a big fan of the Red Sox!
