Wedding cake toppers are small models that sit on top of the cake, normally a representation of a bride and groom in formal wedding attire. This custom was dominant in weddings in the 1950's where it represented togetherness. The bride and groom could then save the topper and display it in their home as a nice reminder of their special day. Modern weddings have embraced more variety in design and significance.
Wedding toppers today are often figures that indicate shared hobbies or other passions. If you google "wedding toppers" you will find an endless selection of toppers for every possible style of celebration: traditional, monogrammed, unique/unusual, theme, humorous and even toppers for anniversaries. While the choice seems endless, try to focus on what you and your fiance want to represent to your guests and choosing a cake topper should be easily checked off your list of "to-do's before I do".
