Claude Montana is back. Sorta. According to WWD, reclusive '80s powerhouse designer Claude Montana will have three designs featured in Eric Tibusch's couture show this evening. Montana's presence was teased as a mere "C.M." on the invitations.

Who better to replace the void left by Nicola Formichetti at Mugler than Manfred Thierry Mugler himself?
