Dandyism, Sophistication
Noun and な adjective
だて
伊達巻きはおせち料理の中で私が好きなものの一つです。
Of all the food served during the Japanese New Year, rolled omelette is one of my favorites.
If you attain Italy-ness, you are becoming like the Italians. In this case, that's pure elegance and dandyism. Also sophistication. Mamamia!
