The Sister Act - Jacqueline Kennedy Onassis and Princess Caroline Lee Radziwill.

There couldn’t be a more apt pair that does justice to the term ‘awesome twosome’ than sisters Jacqueline Kennedy Onassis and Princess Caroline Lee Radziwill.

While Jackie, wife of John F. Kennedy, was known the world over as one of the most stylish First Ladies of the United States of America, Caroline was the more demure but no less glamorous, younger sister. She herself became a royal upon her marriage to Prince Stanisław Albrecht Radziwiłł.

The two sisters were known to paint the town red with their entourage, all of who belonged to the crème de la crème of the American and European societies. Pictures of the gorgeous duo on yachts in the Mediterranean Sea and at balls in New York and Paris were ubiquitous.

Although their lives looked full of privilege, glamour, and all things beautiful, the truth was that both the women underwent many a tragedy through the course of their lives. For Jackie, it was the unfortunate assassination of her then President husband John, in 1963, along with enduring the death of two of her infant children. For Caroline, it was the crumbling of three of her marriages, along with no particular success in her acting career.

However, in spite of their turbulent personal lives, the two made sure they never looked distressed. They always looked like Park Avenue Princesses in everything that they wore.

Some of the most famous images of the two sisters are on their trips to India and Pakistan in March 1962, when Jackie was still the First Lady of America.

They lived in some of the most glamorously-appointed homes in London, New York, Paris, and Greece and continuously made it to the Best Dressed Lists of all the major publications of the world.     - Suneela
