Fear not, fans of all black everything, there is a way to do it without looking like a (total) witch!
Allison Williams shows us her impressive take on coven chic in this Oscar de la Renta dress. The high-neckline and cap sleeves provide the kind of coverage typical of a mysterious sorceress, but in black lace they give the Girls star a sexy edge. The same goes for the way the fabric extends beyond the slip, showing off a little leg.
The look is finished off with bare legs and peep toe pumps, which are both very un-lady-of-the-caldron like.
