Designer Sophie Theallet isn’t a fan of President-elect Donald Trump and has announced she’s refusing to dress the next first lady, Melania Trump.

“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,” Theallet wrote in an open letter she posted to Twitter on Thursday. “The rhetoric of racism, sexism, and xenophobia unleashed by her husband’s presidential campaign are incompatible with the shared values we live by.”

Theallet, 52, is a French-born designer who grew to prominence by dressing current first lady Michelle Obama on a number of occasions.

“As an immigrant in this country, I have been blessed with the opportunity to pursue my dreams in the USA,” she added. “Dressing the First Lady Michelle Obama for the past 8 years has been a highlight and an honor. She has contributed to having our name recognized and respected worldwide.”

In addition to eliminating herself from the potential list of designers who may dress Trump during her tenure, Theallet is calling on all designers to join the boycott. “Integrity is our only true currency,” she wrote.

Trump’s fashion choices this election season have garnered much attention. She famously wore a $1,100 hot pink Gucci p---y-bow silk top to the second presidential debate. On election night, she wore an all-white off-the-shoulder Ralph Lauren jumpsuit.
