Showing up to a party in the same dress as someone else can be a fashion faux pas for both wearers and the Harvey Nichols Christmas 2012 commercial exaggerates what could happen if super powers became involved.
The commercial takes place at a festive holiday get-together, but soon turns grim when two of the guests spot each other only to discover that they've both worn the same outfit. Furious, one girl shoots lasers from her enraged eyes to destroy the other one, but is retaliated against by her opponent who fires right back. The hilarious viral advertisement continues on with both girls battling for the chance to be the sole survivor and to wear their dress with pride. However, when one finally defeats the other, another guest wearing the same dress steps in to settle the score.
