Casual Elegance, the style I like
What Is Casual Elegant Dressing? By Andrea Campbell: Sometimes an invitation comes with its own code for appropriate attire, such as "dressy casual," "cosmopolitan," "fashion-forward," "business casual" or "casual elegant," just to name a few. Because the word "casual" is an antonym for "formal," this may sound like an oxymoron. But the phrase does have meaning.
