* κομψός (kompsós): This is probably the closest single word and is often used to describe something stylish, refined, and graceful. It emphasizes neatness and sophistication.
* λεπτός (leptos): This means "thin," "delicate," or "subtle," and can be used to describe something elegant in a refined, almost fragile way.
* χαριτωμένος (charitōmenos): This means "graceful" or "charming," and implies an elegance that is pleasing and attractive.
* ευγενής (eugenēs): This means "noble" or "high-born," and can be used to describe an elegant person of high social standing or refined manners.
The best choice depends on the context. For a stylish dress, κομψός (kompsós) would likely be best. For a delicate piece of jewelry, λεπτός (leptos) might be more suitable.
