On January 24, 2011, Karolina was one of the most talked-about models of the grand show organized by the French lingerie brand in the style of the Victoria's Secret shows. She notably opened the show in an underskirt holding a real living lamb. Later on in the show, she returned to the catwalk wearing a billowing black kimono complete with a five-meter train. When she was entering the catwalk, the garment's train slipped off the catwalk and got stuck under it, forcing Karolina to remove her whole cloak, to the audience's applause. The incident was widely reported in the media, to the point that the brand Etam published a video of it on their official YouTube channel.
