Princess Sofia of Sweden shows off baby bump in a stunning red dress - as she is joined by husband Prince Carl Philip and other royals for State Opening of Parliament in Stockholm

Princess Sofia of Sweden showed off her baby bump in a stunning ensemble today as she was joined with her husband for the State Opening of Parliament. 

The royal stepped out in Stockholm, the Swedish capital city, alongside Prince Carl Philip, today.

The couple told the public that Sofia is pregnant with their fourth child last week in a sweet announcement. 

Sofia sported a red velvet dress with a belted waistline, highlighting her bump and she paired this with a pair of nude heels.

The 39-year-old accessorised her fashionable look with a ruby-red clutch bag and with a pair of statement gold earrings.

The mother looked glamorous in heavy makeup, consisting of a smoky eyeshadow with lipstick and also wore her brown tresses down in a bouncy curly blow-dry - having earlier in the day opted for a chic black dress.

Prince Carl Philip looked cheerful and content as he proudly stood with his wife and looked dapper in a navy suit. 

The State Opening of Parliament is held every year in September, where the Monarch, King Carl XVI Gustaf, declares the new session open during the ceremony. 

A concert was also be held in collaboration with the Royal Swedish Opera for members of the Riksdag and invited guests, including the Royal Family and members of Government. 

The red frock was for her evening look, however, during the day, Sofia looked like a vintage beauty in a spotty belted dress.

The gown featured fur around the end of the long-sleeves and she paired the ensemble with black heels, a clutch bag and a fascinator.    

For her daytime look, Crown Princess Victoria, 47, wowed onlookers in a slim, bodycon black and white patterned dress, which featured a high, modest neckline and puffy ballooned long sleeves.

She paired the chic frock with a large black belt which highlighted her slim, stylish frame. 

The heir to the Swedish throne paired her ensemble with a pair of sophisticated black gloves, a matching envelope clutch bag and a pair of smart pointed heels. 

She opted to wear her shiny brunette tresses down in a low bun, paired with a trendy white statement headband. 

The mother-of-two kept her makeup minimal, donning only a touch of eyeliner, mascara and foundation and paired her ensemble with a pair of regal silver pearl earrings. 

Victoria also appeared in high spirits today as she smiled for the cameras alongside her husband, Prince Daniel, 50, and modelled her second looks of the evening in a black and white floral dress.

He looked dapper in a matching navy suit that he paired with a crisp white shirt, blue tie and black polished shoes. 

Taking style inspiration from her daughter, Queen Silvia, 80, also stepped out to the annual even in a monochrome outfit. 

She donned a white long-sleeved top which had a onyx-coloured trim around the hem, along with a matching pencil skirt.

She, like Victoria, chose to pair this with a black clutch bag and small, comfortable heels, along with a matching fascinator.

Silvia looked elegant in a matching pearl jewellery set consisting of a diamond brooch, earrings and sizable necklace. 

The Queen wore her chocolate locks down in a short, wavy blow-dry and wore natural makeup for the event. 

Victoria's father, King Carl XVI Gustaf looked well-dressed in an all-black suit paired with a white shirt, grey patterned tie and polished shoes. 

Elsewhere, Princess Madeleine, 42, also made an appearance, sporting a halterneck-style grey maxi dress, along with black open-toe heels and diamond earrings. 

Her husband, Christopher O'Neill, 50, matched with Prince Carl Philip and Prince Daniel, also opting for a navy blue suit.  

During the event, Prime Minister Ulf Kristersson made a speech outlining the Government's plans and priorities for the upcoming year. 

The Royal Anthem is also played in the Chamber, alongside the National Anthem and other performances.
