Princess Estelle stole the show at Te Deum thanksgiving service for her newborn brother in the royal Palace of Stockholm on Thursday. The 4-year-old who has now become a big sister was seated alongside her father prince Daniel in the church. Her grandparents, uncles and aunts also attended the special church service for Prince Oscar Carl Olof.

The 42-year-old Daniel looked after Estelle during the ceremony. The little princess wore a pink dress by children's wear designer Marie Chantal with a matching coat. The coat was borrowed from her aunt Princess Madeleine who used to wear it during her childhood.

Estelle also teamed up a pair of matching thigh-high socks for the occasion and black strappy belles. The little girl completed her look with a bow in her blond hair and carried a pink handbag. She reportedly looked animated and happy after becoming a big sister.

Meanwhile, Princess Sofia showed off her blossoming baby bump in a silver gray dress that featured floral lace detailing. The 31-year-old princess’ knee-length dress featured long sleeves, round neckline and a slight slit at the back. She accessorized with a matching fascinator with mesh detailing and a black box clutch.

Sofia finished her look with a pair of black suede high heels. The princess who is expecting her first child with her husband Prince Carl Philip walked hand in hand with him. The 36-year-old prince looked dapper in a black traditional coat paired with dark gray striped trousers.

He was dressed in a white shirt, a pale gray silk tie and white pocket square. Carl Philip paired his outfit with black lace-up shoes.

Princess Madeleine, 33, and her husband Chris O’Neill who flew from London complemented each other in black. The princess who has two kids — Princess Leonore and Prince Nicolas — looked stunning in a black dress paired with matching high heels. Her long brunette tresses were left loose over her shoulders.

Talking about little Estelle, Swedish parliamentarian Urban Ahlin reportedly told a local publication, just before the church service that the latter was a little disappointed that her baby brother had his eyes closed all the time when she met him and could not see the drawings she had made.

King Carl XVI Gustaf and his wife Queen Silvia were also present on the occasion along with other members of the Bernadotte family.
