"Oshin" and "Carnation" are both asadora dramas. They are set in some of the same time periods, most notably WWII. "Carnation" focuses completely on dressmaking, while "Oshin" only dabbles in that job a bit. The last several weeks of each are really where they are the most similar. In both, the main actress is taken over by an older actress. The plot also shifts to focus on their children more. I recommend both though I'll admit that their stories aren't consistent all the way through.
