Fiona the Flower Girl
I wish this book was available when I got married! I totally would have picked up a couple of copies for my nieces.

This picture book is the perfect gift for soon-to-be flower girls. Girls will enjoy reading the story of Fiona, a first-time flower girl who discovers how exciting it is to play a special part in a wedding. The book includes a flower-shaped keepsake necklace the child can wear, as well as a comprehensive guide for parents with tips on how to prepare girls for the big day.
Oh, and I was pleasantly surprised to see that the book is illustrated by Lorena Siminovich (of Petit Collage). Sweet.
