In case you didn't know, the Balmain x H&M collection is a hot new clothing line.
It's the work of Balmain creative director Olivier Rousteing, whom the New York Times described as "A social media maestro and the selfie-made star of Paris fashion with 1.6 million followers on Instagram."
The paper says he has "whipped up an online frenzy in the weeks preceding the unveiling with the help of celebrities such as Rihanna, Kylie Jenner and Gigi Hadid."
