The Dolce and Gabbana logo, like many of fashion company logos,  is very simple in design.  Composed completely of type, the logo consists of a black san serif font on a white background. The company itself was founded by two Italians in 1985 and the company focuses on clothing and accessories.  I love fashion but sadly I am unfamiliar with this logo, unlike those who purchase products from the company.  It doesn't seem as though the logo has changed since the company was started which has most likely helped with the brands popularity and recognition.
