JoomlaPraise have released a theme geared towards someone getting married. You might think this is a bit too specific but the theme is easily changed and it could be used for anything.
There is also an added bonus in so much that it was built with the K2 article management component in mind so if it is something you are going to want to use or are using, this theme will fit like a glove.
The theme comes with seventeen module positions, three colour themes, custom module heights and lots more including the ability to pick your font family.
The theme also comes with PraiseMenu and PraiseSlides, loads of tutorials on how to change header images and logos and you also get the source files so if you really want to go to town, you have everything you need.
