Be Delicious

This ad is pretty self explanatory.  The main thing that they are trying to say is that this perfume smells "delicious."  The main color is green and there are apples in the back ground, and the color of the perfume is a light green.  So the sent of the perfume in sour green apple.
The thing that I see that they are inferring is that green apples are delicious.  Some people don't like green apples, like me, so I don't think that a perfume that smells like apples will really attract people to buy it.  One thing that I saw, that I didn't see before was the empire state building reflection on the perfume bottle/apple thing.  That, not necessarily advertises New York itself but rather the place it's coming from.  And the name is DKNY also bringing up New York.  It kind of represents New York.    
But the main target audience is women of about ages thirteen to the mid to upper thirties.    
The advertising techniques used in this ad are weasel words, plain folks,  and glittering generalities.
Weasel words are in here, only one that I see, are delicious.  It is saying to be delicious so buy this product to be delicious, but you do not know for sure if it will smell delicious or not.
Plain folks is in here because anyone can by perfume and it is not overly expensive to make it not available for people to buy.
Lastly glittering generalities in this ad is the woman with the apple.  It looks somewhat "yummy" and "sexy" and of course delicious.
