"As one who celebrates and strives for diversity, individual freedom and respect for all lifestyles, I will not participate in dressing or associating in any way with the next First Lady," Sophie Theallet wrote in a letter this week.

“The rhetoric of racism, sexism, and xenophobia unleashed by her husband’s presidential campaign are incompatible with the shared values we live by,” Theallet wrote about President-elect Donald Trump Donald John TrumpOmar fires back at Trump over rally remarks: 'This is my country' Pelosi: Trump hurrying to fill SCOTUS seat so he can repeal ObamaCare Trump mocks Biden appearance, mask use ahead of first debate MORE.

“I encourage my fellow designers to do the same,” she continued.

“I am well aware it is not wise to get involved in politics,” the fashion maven wrote. “That said, as a family-owned company, our bottom line is not just about money. We value our artistic freedom and always humbly seek to contribute to a more humane, conscious and ethical way to create in this world.”

Theallet appears to be the first designer to snub Melania Trump before the former model moves into the executive mansion. While other designers have spoken out against Donald Trump, they’ve still expressed a willingness to dress his wife.

"It would be hypocritical to say no to dressing a Trump," Marcus Wainwright of Rag & Bone, told The New York Times last week. "If we say we are about inclusivity and making American manufacturing great again, then we have to put that before personal political beliefs."

In her Thursday note, Theallet — whose outfits Michelle Obama has worn on multiple occasions — wrote, “As an immigrant myself in this country, I have been blessed with the opportunity to pursue my dreams in the USA. Dressing the First Lady Michelle Obama for the past 8 years has been a highlight and an honor.”

"The Sophie Theallet brand stands against all discrimination and prejudice,” wrote Theallet, saying the brand's runway shows, ad campaigns and celebrity dressings have been "a celebration of diversity."
