mystique
I think you'll agree this theme has a certain mystique to it. This fun, colorful theme is flexible enough to fit any type of site — it's simply loaded with options. A long-time favorite for self-hosted sites designed by digitalnature, Mystique is now available in your WordPress.com dashboard.
What doesn't this theme do? It offers layout choices of one, two, or three columns, six color schemes, four footer widget areas, and support for four post formats. Not to mention built-in links to your favorite social networks in the header, a unique custom widget with quick-switching tabs, and special treatment for a "featured" post at the top of the site.
