Means 'elegant' or 'refined'. Focuses on graceful, tasteful behavior and appearance, often associated with good breeding.

Emphasizing family background and proper upbringing rather than just current behavior.
Means 'from a good family'. Directly references lineage and social standing. Slightly formal.
