Juicy Couture has really cute charm bracelts and charms. They are avialble at high end in department stores or their website.
I also like the Troll Bead charm braclettes. They are more modern but still have a classic charm. They are more artistic and would be better for some one a little older (or some one growing up too fast!). These little beads are stacked and added to tell a story. The website offers a lot of different colors and designs so you can create a bracelet that matches the colors and look of your wedding.
