Fashion designers are protesting the election of Donald Trump by refusing to dress the incoming First Lady, People magazine reported.

The first major designer to go on the record did so on Twitter. Sophie Theallet, who has dressed Michelle Obama for the past eight years, said her decision was made in protest to "discrimination and prejudice."

"As an independent fashion brand, we consider our voice an expression of our artistic and philosophical ideas. The Sophie Theallet brand stands against all discrimination and prejudice. Our runway shows, ad campaigns, and celebrity dressing have always been a celebration of diversity and a reflection of the world we live in," she wrote in an open letter that's making waves in the fashion world.

Theallet encouraged other designers to do the same, and according to People, other designers have for the past few months refused to lend items to the Slovenian former model or Trump's daughters, Ivanka and Tiffany.

Earlier this week, Ivanka Trump's jewelry company apologized for marketing a $10,800 bracelet she wore during last weekend's "60 Minutes" interview.

The company said a "well-intentioned marketing employee" sent out the alert on social media, not realizing the "customary protocol."

Ivanka Trump Fine Jewelry said it would be reviewing its policies and procedures in light of her father's victory.
