Lady Gaga arrived in Paris with fiancé Christian Carino and immediately kicked off what promises to be a Fashion tour de force. In the span of a single day, she transformed from a midi-dress-wearing Lady who lunches to a slick, high-fashion club kid like that.

For her first look, Gaga was the picture of retro elegance. She stepped out in a ladylike red tie-neck midi dress from CO's fall collection, finishing off her vintage-inspired outfit with Lorraine Schwartz earrings, Kuboraum cat-eye sunglasses, and a black leather Balenciaga handbag. Seemingly having had enough of the retro-ladylike vibe, she then flipped the script entirely, changing into a glossy electric blue trench, complete with metallic green bra and platform boots. Don't you dare try to pigeonhole this fashion chameleon.

As for us, we're fans of both looks - and we're suddenly acutely feeling the lack of vinyl outerwear in our wardrobes. If you're with us, check out both of Gaga's Parisian outfits from every angle, then shop lookalike versions for yourself.
