Kim Kardashian (@kimkardashian)

Kim Kardashian's Instagram with over 360 million followers remains the gold standard for luxury brand integration and aspirational lifestyle content, though she trails #3 Ariana Grande by approximately 20 million. Her Skims shapewear brand and SKKN beauty line are almost entirely Instagram-native businesses, and her account is studied by marketing schools as a masterclass in direct-to-consumer social commerce, with Skims generating over $400 million in sales from Instagram-driven traffic in 2023.
