Is there a word or a phrase, describing the refinement (in the sense of sophisticated and superior good taste) of shapes in the context of some solid artistic works (such as pottery or sculpture)? I thought of shapely, but I'm not sure if it could be used in a non-suggestive context.
EDIT: The sentence, which contains the word or phrase should be: "The vase we've seen in the museum was amazing"—but with a word or phrase in place of "amazing" that describes the refinement of the vase's shapes with reference to its general shape and its relief details). That's one example that I can invent quickly, but it's going to be used regarding not vases literally, but some everyday things.
EDIT2: If you don't know such word or phrase, but have some thoughts regarding shapely, please share.
