The launch of Carine Roitfeld's new magazine, CR Fashion Book, hasn't been without its controversies. As you will know, Condé Nast reportedly banned several photographers, models and stylists from collaborating with the former Vogue Paris editor but despite all of that, Roitfeld is flying high. The preview of the issue has gone down well and this weekend, just about everyone turned up to congratulate her at the party she hosted to celebrate the debut issue.

'It's very different from my last party,' she told The Cut, having a look at the guests in the marble-floored atrium of the Frick Museum. Around the same time last year Roitfeld through a karaoke party to celebrate her Barneys campaign at a strip club on the West Side Highway so basically the polar opposite of this year's swanky 'do. 'I want to do something different, more classic,' she said about the formal Mercedez Benz-sponsored black tie event. 'After all, I am a grandma now.'

Christian Louboutin's 20th anniversary is the celebration that keeps on giving. The past few weeks has seen the brand host several key initiatives to mark the big milestone and last night the fun continued.

Barneys New York hosted a cocktail party for the brand, in conjunction with the big reveal of the Louboutin window display taker over, which was attended by everyone from the Mary Kate and Ashley Olsen to Virginia Smith and Calvin Klein.

Last night was the night that we had all been waiting for as Kanye West finally debuted his collection for KW by Kanye West in Paris during fashion week, to much anticipation. As you would expect, just about everyone was there. “I did not want to miss it,” Linda Fargo, the fashion director of Bergdorf Goodman, told The New York times and that seemed to be the sentiment of the all guests yesterday.

Fargo was joined by Jared Leto, Mary-Kate and Ashley Olsen, Leigh Lezark, Lindsay Lohan and Ciara. Designers like Alexander Wang and Azzedine Alaia sat alongside Anna Wintour and Glenda Bailey.
