President Donald Trump is set to give his first address to a joint session of Congress. Among those in attendance will be the newly appointed DNC chairman Tom Perez and a troupe from the Democratic Women’s Working Group—all dressed in white.

The Women’s Working Group planned on attending the speech, which will commence Tuesday evening at 9 p.m., and were all encouraged to wear white by the heads of the group in a letter that was released Monday by Florida Rep. Lois Frankel, the Associated Press reported Tuesday.

The women were told to wear white, in honor of women’s suffrage, and in a move to “stand in solidarity with the women of our nation.” The letter sent by Frankel, who is also chairwoman of the Women’s Working Group, was also directed to additional women members of the House.

Hillary Clinton famously wore a pantsuit to Trump’s inauguration in January. The colors white, gold and purple were symbolic colors of the National Women’s Party and were to represent the following: gold, for “the color of light and life" and “the torch that guides our purpose.” Purple was for “loyalty, constancy to purpose, unswerving steadfastness to a cause,” and white represented “the emblem of purity, symbolizes the quality of our purpose,” according to the National Woman’s Party website.

Trump’s speech to Congress is expected to outline for his political agenda. Following an interview Tuesday morning with “Fox and Friends,” Trump graded his presidential efforts with an “A.”

"In terms of achievement, I think I’d give myself an A. Because I think I’ve done great things. But I don’t think I have – I and my people – I don’t think we’ve explained it well enough to the American public," Trump had said during the broadcast. "I think I get an 'A' in terms of what I’ve actually done, but in terms of messaging, I’d give myself a 'C' or a 'C-plus.'"

Former Kentucky governor Steve Beshear will also be in attendance to give the response for the Democrats and will be expected to defend the Affordable Care Act.
