Cupcake towers are a popular alternative to the traditional wedding cake. Many times cupcakes can be cheaper than a wedding cake and you can get a wide variety of flavors. I love how these two pictures have a wedding cake at the top so the bride and groom can save it for their anniversary. If you decide to do cupcakes instead of a wedding cake check and see if it will be cheaper for you to buy boxes of cupcakes and then get a cupcake stand, instead of saying you want 100 cupcakes for a wedding and the bakery providing the stand.
Cupcake Flair on Etsy sells this cupcake stand that can hold 150-300 cupcakes for $48.95. You can dress up this stand with ribbon or fabric so that it fits in with your wedding.
