It was on NetFlix, but it may have moved off.
It follows a Sephardic family in Jerusalem from about WWI (Ottoman), through WWII, the British Mandate, through the founding of modern Israel.
It’s (very) loosely based on a true story of a fashion designed (the female protagonist) who became the leading designer in France in the 60s-70s.
Had a bad crush on the female lead.
