Either $wgServer is set incorrectly in LocalSettings.php, or (less likely) something like $wgStylePath is set to some absolute path containing localhost in your LocalSettings.php.

Go through all the Path related variables in LocalSettings.php and look for anything containing Localhost in it (or anything that would make sense on your local computer, but not when accessing the site remotely). You can also try something like firebug's network pannel to see where the requests for stylesheets are going.
