Queen Elizabeth II showed off her thrifty side by recycling an aqua green tweed coat and a matching hat to open the 5th session of the Welsh assembly, also known as the Senedd on Tuesday. With her husband of 68 years, Prince Philip by her side, she was welcomed by tunes played by Prince Charles’ personal harpist. The nonagenarian royal had a pre-birthday celebration in Cardiff.

As Elizabeth and Philip stepped out of train, a 21-gun salute was fired in her honor in Cardiff Bay. The couple were accompanied by Prince Charles and his wife Camilla, the Duchess of Cornwall. The Welsh tour was part of the queen’s tour to the four corners of the U.K. in her 90th birthday year.

The stylish royal opted for an aqua green silk tweed coat. She paired it with a turquoise, grey and ivory silk dress. Her outfit was courtesy Stewart Parvin, which she paired with a matching hat by Rachel Trevor Morgan with oversize floral accents. Her coat featured long sleeves, and chunky silver buttons.

Elizabeth accessorized with a three-string pearl necklace, matching pearl earrings and a diamond brooch. She wore white gloves and carried her famous black Launer handbag. The queen completed her look in a pair of her trusted black shoes and a slick of red lipstick.

Inside the Senedd, the royals and assembly members were serenaded by songs from the National Youth Choir of Wales. Besides, a specially commissioned poem was read by Maeve Tonkin-Wells, a student from the Royal Welsh College of Music and Drama. The queen was wished by the members and presiding officer for her official birthday.

“She has a delightful sense of humor. A wicked sense of humor,” said Dame Rosemary, who sat with her at lunch when Elizabeth was there last time.

Besides, Charles’s personal harpist Anne Denholm played a soft tune on the prince’s harp as the British royal signed a commemorative parchment. Camilla meanwhile was dressed in a green lace dress with an embroidered jacket by Fiona Clare. The queen and Duke of Edinburgh then headed to Cardiff University, whereas Charles also went off to attend another engagement.
