Grazia UK interview
"The music video for “Rockstar 101”  directed by Melina Matsoukas,she is wearing a decked out in a chain bodice and leggings made especially by London-based Swedish designer Fannie Schiavoni. Fannie – whose signature style is creating super fierce jewellery pieces, wrist cuffs and armour style body pieces solely out of metal chains – is hot on our radar and counts Lady Gaga and Yasmin Le Bon as fans. 
“I was working as the assistant to Rihanna’s creative director, Simon Henwood, for upcoming world tour. I discussed ideas with Rihanna and her stylist Mariel Haenn the day before the shoot and then I went to my hotel in LA and made everything that night. The next day was the video shoot and I literally chained Rihanna into everything piece by piece.”
