Is dressing oneself in formal attire on Sundays (Sunday hat and dress) solely an American Christian custom?

Before I start, I realize that this question is *related* to another question . However, this question is more concerned about the **custom** of wearing one's "Sunday best", which usually means a nicely brimmed Sunday hat and modest-looking dress. This has been portrayed in literature and in movies. Example: *Chicken Sunday*, written by Patricia Polacco, and *Bridge to Terabithia* (2007 movie). Is this solely an American Christian custom? Are there examples in other Christian cultures? How did this custom come about, and how did it evolve over time?
