Both blonde beauties stepped out wearing their New York black best for a major A-lister's event. We can't believe the Goop editor and Wild star went bare-legged in the Polar Vortex, but they're making up for it with covered arms and thick fabric. So do you prefer Gwyn's Saint Laurent sparkler or Reese's classic Valentino cut?
There's something so perfectly "Manhattan" about the Iron Man 3 star's sequined mini. It screams night-on-the-town without going too over-the-top. Simple black booties definitely help that cause, as does the LA native's beachy blond locks.
But we can't deny the perfection that is the Mud star's scalloped cut-out top. It's both incredibly modern and yet Reese still looks like Sophia Loren on a red carpet decades ago. A wavy bob and vintage-style shoes complete the vision.
So who wins this LBD debate? We're going to give it to the blonde on the right. Gwyn looks gorgeous, but Reese looks original. What's your take?
