It’s been a rumor for over three months, and now it’s confirmed: Superstar stylist Nicola Formichetti is now the creative director at French fashion house Thierry Mugler, which is owned by Clarins. His first collection will be for Fall 2011.

Formichetti will have two head designers directly under him: Sébastien Peigné for womenswear, and Romain Kremer for menswear. Peigné has spent the last ten years working with Nicolas Ghesquière at Balenciaga, and Hyères-winner Kremer designs an eponymous collection.

The group is quite young and innovative–Formichetti is just 33, Peigné is 30, and Kremer is 28–so it’ll be interesting to see whether or not they turn the house upside down.

Regardless, they’re sure to stay true to Mugler’s original vision. Formichetti is obviously a huge fan–he’s used Mugler’s costumes in a Gaga video or two.
