I have added to my WordPress theme collection. Looking into providing a Wedding Planner site for a potential client and wanted to see what was available in the way of WordPress themes.

I absolutely love this first theme..

Blossom Weddings

The background image of the girl in this theme is removable so I could add another image more representative of weddings without much problem.

Pretty

This theme is really not a wedding theme-- but reminds me of a true online journal type theme-- for a lady talking of career, play, fashion and dates.. no frills-- just life.

Girl's Life Journal

I found several others.. I can customize any look or add any features/plugins to suit your needs...
