Angelababy is opening the third of her chain of Hong Kong eateries and someone thought that she might look like Audrey Hepburn in one of her signature roles, Holly Golightly, "Breakfast at Tiffany's". She looked like herself, lovely as usual. The tiara and ropes of pearls in her hair worked as part of an impersonation or reference; the black leather minidress didn't.
For an interesting contrast here is Hepburn as Holly in glorious black and white.
