Allison Williams has been busy since we featured her in Christian Louboutin’s “Air Chance” slingback pumps at the People’s Choice Awards. This week, she helpfully showed us what toe cleavage is all about.

First, the American actress, comedienne, and musician attended Diane von Furstenberg’s Journey of a Dress Exhibition Opening Celebration on Friday along with Abbie Cornish, Ahna O’Reilly, and Bella Thorne.

Allison wore an Amelia wrap dress from the Diane von Furstenberg Spring 2014 collection styled with white leather Jimmy Choo “Maiden” pumps.

Allison’s Italian-made Jimmy Choo “Maiden” pumps feature buckled adjustable straps and genuine snakeskin leather.
The next day, she hit the red carpet for the 2014 Sean Penn & Friends Help Haiti Home Gala, which benefitted J/P HRO.

For this event, she donned a daring dress from the Osman Fall 2013 collection featuring a gold embroidered front panel. Allison styled the sleeveless cocktail dress with Christian Louboutin’s “So Kate” pumps in mirrored bronze leather.

Toe cleavage, also known as toe crack, is the partial exposure of a woman’s toes in shoes cut low enough at the vamp.
According to Manolo Blahnik, “the secret of toe cleavage, a very important part of the sexuality of the shoe” is that “You must only show the first two cracks.”

Which of Allison’s two red carpet looks do you prefer—her classic Diane von Furstenberg style or the daring Osman dress?
