When it comes to baby showers, you do not have to have a theme that is either pink or blue. The truth is, there are no rules when it comes to the perfect theme for a baby shower. Some people choose to go with basic, neutral, or even western style. Themes can also be princess or transportation-related. As a host for the party, you need to choose what the theme of your event will be and build your invitations to match it. This will ensure that people know what to expect and perhaps what to bring along.
