Below are some inspirations I pulled from the Internet to help give Emily an idea of great simple ways to decorate around this theme.

Here is a beautiful shower with similar colors from a site called The Sweetest Occasion. I love the tea favors and 3 tiered floral centerpieces.
To go along with the girly aspect of this shower I would do a simple tea style buffet with yummy finger sandwiches, fruit tray and cheese board. Use tea pots to serve coffee, tea and water in pretty tea cups. I love the idea of using lettuce cups filled with something as simple as a store bought chicken salad. We have all seen the soup shooter appetizers that are so popular. Well, what about a crudite shooter? These are very cool, and can be found at Hip Hostess!
