Quintessential English rose Lady Kitty Spencer, niece of the late Princess Diana, wore no fewer than five different dresses for her lavish wedding celebration at Rome’s 17th century Villa Aldobrandini over the weekend.

The model and socialite, 30, who tied the knot with 62-year-old retail tycoon Michael Lewis – a multi-millionaire five years older than her father, Diana’s brother Earl Spencer – seized the opportunity to showcase her role as global brand ambassador for Dolce & Gabbana.

But in an unusual break from a century-old family tradition, the bride decided not to wear the so-called “Spencer Tiara” — worn most famously by the 20-year-old Lady Diana Spencer at her ill-fated 1981 marriage to Prince Charles — to the marriage ceremony.

This is notable because Kitty is the first-born child of Earl Spencer and duly expected to fly the Spencer flag.

In addition to gracing Diana’s crown, it also provided the crowning glory for Diana’s elder sisters, Lady Sarah Spencer and Lady Jane Spencer, on their wedding days.

Lady Kitty Spencer’s mother, Victoria, wore it at her 1989 union with Earl Spencer, which ended in bitter divorce.

The Earl did not walk his daughter down the aisle, and reportedly stayed home in England on the Spencers’ ancestral estate of Althorp.

Spencer had reportedly been receiving instruction ahead of their wedding in Lewis’ Jewish faith
