What a fashion faux pas!

Vogue shockingly decided to feature Kim Kardashian on its cover this month, enraging readers who threatened to shun the magazine in protest.

Kanye West spent months groveling to editor Anna Wintour to splash his ample-bottomed fiancée on the front page.

It worked. The couple, who plan to marry on May 24, appear together on April cover, which was shot by Annie Leibovitz.

“It’s so controversial because Anna [Wintour] has been so public that she was not interested in Kim,” says celebrity stylist Phillip Bloch.

The style maven tried to explain her reasoning in her editor’s letter.

“You may have read that Kanye begged me to put his fiancée on Vogue’s cover. He did nothing of the sort. The gossip might make better reading, but the simple fact of the matter is that it isn’t true.”

She wrote that she wanted to “feature those who define the culture at any given moment, who stir things up, whose presence in the world shapes the way it looks and influences the way we see it. I think we can all agree on the fact that that role is currently being played by Kim and Kanye to a T. (Or perhaps that should be to a K?)”

Wintour then praised the couple, calling West a “cultural provocateur,” and adding that Kardashian “through her strength of character, has created a place for herself in the glare of the world’s spotlight, and it takes real guts to do that.”

When images of the magazine’s cover broke Friday, the hashtag #Boycott­Vogue lit up Twitter.

Men’s fashion blogger Alexander Liang tweeted, “I lost all respect for Vogue.”

Kardashian, who has managed not to let the brouhaha ruin her moment, tweeted:
