When Lady Gaga is involved, you can bet this is NSFW. While it was big news that Nicola Formichetti, Lady Gaga's original stylist, would be presenting his first womenswear collection for resurgent Paris design house Thierry Mugler, it might have been bigger news that Vogue March cover girl Lady Gaga would be walking in the show, which was live-streamed yesterday on Facebook. Nicola presented his bevy of models as various versions of Catwoman, wearing dangerously high shoes that caused a few almost-spills. And we're not talking pussycats. More like dangerous, claw-your-eyes-out cats, led by big cat Lady Gaga. She had no problem with the treacherous shoes and later, at the afterparty, wore one of the runway looks with an equally treacherous-looking pair of black boots.
