Tiffany Trump slipped into a very glitzy ensemble as she joined dad Donald Trump to meet the British Royal family during his historic state visit to the UK.

The 31-year-old, who gave birth to son Alexander in May, was accompanied by husband Michael Boulos, 28, for the trip.

The couple were spotted arriving to the state banquet hosted by King Charles III and Queen Camilla, where the President and First Lady are guests of honor.

Tiffany, who entered with Michael behind Kate Middleton and Prince William, opted for a royal blue off-the-shoulder gown which shimmered with sequins.

The stunning piece was covered in small silver sequins at the top of the gown and one small sleeve, which were dispersed down the body and skirt.

Matching blue material dramatically draped across the front of the stunning gown and trailed down the side of her dress, showing off her svelte figure.

She left her shoulders bare and showed off her décolletage, pairing the beautiful gown with black open-toed platform heels and a simple rectangle clutch in the same shade of blue as her dress.

Tiffany wore her blonde tresses out and curled, with one side tucked behind her ears and the other cascading over her shoulder.

She accompanied her glittery look by accessorizing with a choker necklace consisting of two strings of diamonds and delicate drop earrings, with diamond bracelets on each wrist.

Michael, also dressed for the occasion, opting for black tuxedo jacket and a white bow tie.

She followed the style set by the First Lady, Melania, who also bared her shoulders in a daring off the shoulder yellow gown for a state dinner.

The daughter of the U.S. President was seen chatting to Apple CEO Tim Cook, and was also seated next to him for the dinner. Her husband Michael was seated next to the Princess of Wales.

Earlier in the day, First Lady Melania looked effortlessly chic in a Christian Dior Haute Couture dark gray skirt suit that flared out at the waist and fell just below her knees.

She wore her long locks in a slick bun that was largely hidden by a Dior wide-brimmed wool hat in a brighter purple hue – which caused quite a stir.

Melania, 55, was expertly poised in her heels as she walked alongside Donald, Prince William and Princess Kate in the Walled Garden on the Windsor estate.

The group ambled a short distance to meet King Charles III and Queen Camilla outside Victoria House to officially launch the trip.

The Queen spent Tuesday afternoon resting at Windsor Castle, having pulled out of attending the Duchess of Kent’s funeral at Westminster Cathedral after suffering from acute sinusitis – but royal aides said she had recovered to greet the Trumps.

Camilla was photographed wearing a vibrant sapphire blue dress, a matching coat by Fiona Clare and hat by Philip Treacy and a sapphire and diamond brooch. Kate was seen in an Emilia Wickstead dress, a hat by Jane Taylor and a feather brooch.

The President eventually emerged from his Marine One helicopter with Melania – who opted for a floor-length classic Burberry trench coat when she touched down in London yesterday – at 12.16pm, with their arrival celebrated with music.

Trump is making history with the unprecedented second state visit to the United Kingdom with a royal return steeped in politics and the president’s well-known love of pageantry.

‘Trump loves pomp and circumstance, and nobody does it better than the British,’ a Washington insider told the Daily Mail.

On Tuesday, Tiffany looked elegant in a tasteful, navy blue, crepe v-neck gown by the brand Nissa, which featured pearl detailing on the collar and large pearl buttons at the chest.

The dress, which is no longer available but once retailed for $900, was complete with a thin belt at the waist.

She accessorized the glamorous look with a pair of black patent leather pumps with ruched detailing around the toe, as well as an Hermès Epsom Kelly Sellier II 25 in navy blue, which can sometimes sell for over $30,000 at resale.

To tie everything together, the mother-of-one wore a pair of round black sunglasses, keeping her long blonde locks loose as she opted for neutral make-up.

Her husband wore a navy blue suit with a light, sky-blue tie.
