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 took pleasure in softball, volleyball, and basketball, cut classes in high school, and passed much of her time in the art department. She graduated from Hewlett High School in 1966, and then went to the Parsons School of Design.
