The center-parted hair. The right knee pointed out, creating a curve at her left hip.Practically every detail in the photo — right down to the matching short set — looked familiar to Sydney Gifford. So did the woman posed in front of the nondescript white wall.Days earlier, Gifford, a 24-year-old lifestyle influencer, had shared a photo with her thousands of followers that was virtually identical. The woman in this new photo was a fellow influencer, Alyssa Sheil, with whom she had gone shopping and done a photo shoot months earlier. At the time, she thought their interactions had been merely awkward. But as she scrolled through Sheil’s photos on Instagram for the first time in nearly a year, she said, Gifford suspected those meetings had been some kind of aesthetic espionage.Gifford claims that Sheil, 21, not only started to mimic her online persona but also appropriated her entire look. And now she is suing.
