Ivanka Trump dazzled in a light blue strapless gown at the White House state dinner for Xi Jinping.

The 44-year-old boldly flashed her décolletage in Washington, DC, on Thursday evening.

President Donald Trump and wife Melania Trump are hosting the Chinese president and his wife Peng Liyuan in the East Room, where both leaders delivered remarks.

For the event, Ivanka opted for a $6,000 crystal embroidered satin maxi gown by Georges Hobeika.

The one-piece boasted a structured corseted bodice, embroidered lace-inspired scrollwork, intricate floral motifs and accented crystallized fringes.

The mom-of-three wore dark makeup around her eyes and swept her bleach blonde tresses to one side. 

Ivanka was joined at the event by 15-year-old daughter Arabella, whom she shares with husband Jared Kushner.

The impeccably dressed teen, who speaks fluent Mandarin, oozed sophistication in a black backless maxi dress.

The mother-daughter duo posed for a series of snapshots alongside Tiffany Trump and Lara Trump, who looked equally as glamorous.

Ivanka had also been present earlier in the day during an arrival ceremony for China's President Xi Jinping and his wife, Madame Peng Liyuan, on Thursday.

She opted for another figure-hugging blue dress with a matching jacket on top that contained intricate, white floral detailing.

The First Daughter accessorized with some white, two-tiered pearl earrings and completed the look with some simple white pumps.

Ivanka, who was joined by Arabella once again, styled her blonde hair in an updo, leaving two pieces loose in front down to frame her face.

Vice President JD Vance's wife Usha Vance, who welcomed the couple's fourth child back in July, sat next to her. 

Thursday night's lavish black-tie event was one of the most star-studded evenings of the administration, offering a glitzy opportunity to smooth over notoriously fierce geopolitical friction with the Asian superpower. 

Behind closed doors in the East Room, Melania's office said they personally orchestrated the evening's extravagant arrangements, transforming the space with red linens, Reagan-era vermeil, and overflowing urns of crimson dahlias – a striking aesthetic that the First Lady notes 'draws on the color red's longstanding cultural significance throughout Chinese history.' 

As the leaders and their guests dined, there were several performances, including military musicians and inauguration tenor Christopher Macchio setting a grand soundtrack.

Inside the dining room, guests raised glasses of Schramsberg 'Blanc De Noirs' for a symbolic toast, reviving the historic 1972 'Toast to Peace' between Richard Nixon and Premier Zhou Enlai in China.

White House chefs fused classic American ingredients with subtle Asian flavors across a lavish multi-course menu.
