Princess Kate, daughter Charlotte honor Queen Elizabeth with sweet details in funeral attire

Catherine, Princess of Wales, and her daughter, Princess Charlotte, dressed up their black looks for Queen Elizabeth II's funeral with sweet details that honored the queen.

The mother and daughter duo, who attended the state funeral for Britain's longest-reigning monarch Monday at Westminster Abbey

both wore simple black dresses topped with black overcoats, paired with black tights and black shoes.

But their jewelry choices paid tribute to a beloved matriarch.

On Princess Charlotte's coat, she wore a dainty brooch in the shape of a horseshoe, a tribute to the queen, her grandmother, who had a lifelong passion for horses.

Princess Kate, the wife of Prince William, wore two pieces of jewelry that once belonged to her grandmother-in-law.

She wore Bahrain Pearl Drop Earrings and a four-strand pearl choker necklace, both from the queen's collection, People reported.
