Biography
Princess Soamsawali was born on 13 July 1957 at Guy's Hospital in London, United Kingdom. She is the eldest child of Mom Rajawongse Adulyakit Kitiyakara. Her father was an elder brother of Queen Sirikit and her mother is Thanpuying Bandhu Savali Kitiyakara (born Princess Bandhu Savali Yugala). She has one younger sister, Mom Luang Sarali Kitiyakara, born 8 April 1966.

Her father was the second child of Prince Nakkhatra Mangkala Kitiyakara, the Prince of Chanthaburi II and Mom Luang Bua Snidvongs. Her mother was the daughter of Prince Bhanubandhu Yugala and Mom Luang Soiraya Snidvongs.

She first attended the primary level at Chitralada School, then moved to Chiang Mai with her father when he was a judge at the Chiang Mai Court. She moved to study at Regina Coeli College, the all-girls academy in Chiang Mai in 1967.

Personal life
On 3 January 1977, at the age of 19, she married her first cousin, Maha Vajiralongkorn, the only son of King Bhumibol Adulyadej. After their marriage, her official title became Her Royal Highness Princess Soamsawali, Royal Consort of His Royal Highness Crown Prince Maha Vajiralongkorn of Thailand (). The couple had one daughter, Princess Bajrakitiyabha of Thailand, born on 7 December 1978. The marriage ended in divorce in 1991.

After her divorce from the crown prince, the king, by royal proclamation, gave her a new title on 12 August 1991. Her official full title became Phra Worarachathinatdamat (), meaning the mother of the king's first grandchild (translated into English as The Princess Mother of the King's First Grandchild). She thus retained her title as princess and remains a member of the Thai royal family. In 2019, she was granted a new title and the higher rank of "Krom Ma Meun" by King Vajiralongkorn.

Princess Soamsawali has an adopted daughter, Siraphatchara Sophatcharamani or Bai Phlu.

On August 27, 2018, Princess Soamsawali was admitted to the Chulalongkorn Hospital for treatment of a swollen shin of the right leg, which was diagnosed as a tissue infection. Her condition improved after being receiving medication until she experienced weakness in her right hand. In 2019, she suffered a brain hemorrhage and was admitted to Chulalongkorn Hospital for medical treatment.
