My friend really like Donna Karen. She is an American fashion designer. 
I am not familiar with her.  What kind of stuff does she design? Dresses?
Donna Karens's clothing label is DKNY. It stands for Donna Karen New York. She makes all kinds of stuff.
Ooohhh. I recognize that name now.  That makes sense.  I dont own any stuff by her though.  I think its expensive.  is it?
Some of it can be. Donna Karan attended the Parsons School of Design in 1966.
