Participants reported that they liked the advertisement more—and more likely would buy the advertised items in advertisements—with a not digitally enhanced plus-sized female model, because of the perceived authenticity of the model. The results of this investigation also suggest that attitude toward the advertisement and purchase intention were highest when a plus-size model who was not digitally enhanced was featured on a women's clothing brand's Instagram account.
