UK fashionista fave TopShop just opened its first NYC store. Wheatpaste adverts abound. And next to some of the official ads, lurk posters that seem to poke fun at spokesmodel Kate Moss and the brand. Yet they are rather harmless and in keeping with both the brand spirit and aesthetic.

So it makes me wonder if the snarky posters are in fact from the agency running the campaign. Are they creating their own point/counterpoint in an effort to further place the brand within the streetscape dialogue? Is it an effort to make TopShop look all the more fresh and that people care enough about it to talk it out? And if so, where does this fall within the rules of slang and advertising?
