Get posts by tag OR with the given category

So I have posts & custom post types. They can be either categorized in fashion or tagged with featured. So I want to pull the posts within that category or tagged with featured. This is what I have so far..

$fashion_args = array( "post_type" => "any", 'tax_query' => array( array( 'taxonomy' => 'category', 'field' => 'slug', 'terms' => 'fashion', ), ), "tag" => "featured", "posts_per_page" => 10 );
