U.S. first lady Michelle Obama wore a custom-made, floral-patterned jacquard dress by the Taiwanese-Canadian designer Jason Wu during the state dinner for Canadian Prime Minister Justin Trudeau at the White House Thursday evening. Canadian first lady Sophie Grégoire-Trudeau, meanwhile, stunned in a purple Lucian Matis dress with pink lace details. 

The first lady wore her hair down in luxurious curls, and her flowing, strapless dress bore a bold red and chartreuse floral pattern. At one point, Michelle Obama greeted Grégoire-Trudeau with a kiss after earlier calling her a “soulmate.”

Trudeau's visit marked the first state dinner for a Canadian leader in 19 years. He posed for a picture with President Barack Obama and their wives as the leader of the United States declared the Canadian couple “spiffy looking."

The world leaders discussed weightier topics earlier in the day, announcing joint efforts to curb methane emissions. Obama praised Trudeau's liberal politics in a welcome ceremony decked out in American and Canadian flags. 

“He campaigned on a message of hope and of change; his positive and optimistic vision is inspiring young people,” Obama said of Trudeau at a news conference in the White House Rose Garden. “On the world stage, his country is leading on climate change and cares deeply about development, so from my perspective, what’s not to like?”

Grégoire-Trudeau represented Canadian fashion throughout her trip to the States. The prime minister's wife, who has been compared to such style icons as Michelle Obama, Kate Middleton and Jackie Kennedy, stepped off the plane at Andrews Air Force Base wearing a pantsuit by the Montreal-based Vietnamese-Canadian designer DUY. During her first White House visit, she donned a red and fuchsia dress with an asymmetrical floral pattern by Romanian-born designer Matis.  She completed the look with hot pink "Amelia" heels by Canadian designer Zvelle.

The guest list for the state dinner included many Canadians who have become household names in the U.S., including actors Michael J. Fox, Mike Myers and Ryan Reynolds. NHL Commissioner Gary Bettman and NBA Commissioner Adam Silver also made the cut. 

The menu includes an Alaskan halibut casserole, followed by a roasted apricot galette with Appalachian cheese, baby lamb chops with Yukon potatoes and maple pecan cake.
