Gap caused an uproar after sharing a photo of a very skinny model on Twitter.

"Dress up your days in pastel plaid. #since1969," the clothing company wrote on Aug. 4 along with a photo of a model in a dress.

Many Twitter users quickly commented on the model's weight and criticized the company for using her in an advertisement.

"Doesn't the Gap feed it's models? Seriously she looks ill. Please use healthy looking women in your ads next time," one wrote.

"We need to see REAL women in ads. I mean, after all, REAL women buy clothes," wrote another.

Another wrote, "Look at the size of her head in proportion to her cadaver like body. Shame on you!"

The company quickly issued a response. "Our intentions have always been to celebrate diversity in our marketing and champion people for who they are," spokesperson Edie Kissko said in a statement. "Upon reflection, we understand the sensitivity surround this photograph. Customer feedback is important to us and we think this is a valuable conversation to learn from."
