The other day (Oct. 5), Calvin Klein threw a pop-up event serving some Amazon-style Fashion.

Guest were entertained by games, prizes, exclusive product drops, and a wide range of interactive attractions. But the biggest highlight of the event was the surprise performance by CK collaborator ASAP Rocky.

Rocky made his guest appearance and performance on Friday night at NYC’s Flatiron Plaza. He performed a medley of new and old records, including “Praise the Lord,” “L$D,” “ASAP Forever,” and “Raf,” which is a track named after Calvin Klein’s chief creative officer Raf Simon.

The CK x Amazon Fashion event continued all through Saturday and the concluded show will start today (Oct. 7) at 11 a.m.
