Burberry is an old brand name that has had a reputation to be high end, expensive and signature plad design.  Burberry has numerous print ads in the more high end magazines such as vogue. To up the anti they put in a huge celebrity in their campaigna nd who has a bigger name than Emma Watson.  She is one of the most successful starlets of our times thanks to Harry Potter.  

To top this they ad her model brother into campaigns such as this.  

Then if siblings are not enough publicity for the brand, they take advantage of her relationship with the lead singer in the band One Night Only.  Granted they are not together anymore, (and what celebrity couple actually lasts forever) but the power couple ruled the designer ads for a very long time)
