Menswear has never looked so feminine. Supermodel Karolina Kurkova sported a Dsquared² black silk suit jacket and a white button-down to the Pirelli Calendar's 50th Anniversary dinner. She styled her ensemble with a bowtie, leather shorts, black heels, and an array of silver rings.

She may not have made it to space yet, but Lady Gaga sure looks otherworldly. The singer casually sported a leather-like, turtleneck ensemble by Slovenian designer Peter Movrin (that retails for $9,543) at LAX on Monday.
