Do you much about the clothing brand Donna Karan?
I seem to remember something about Donna Karan creating those DKNY jeans that were all the rage when I was younger.
oh yes, those were very popular back in the day.  
You can see her latest things in the Club 21 retails stores across the world.
She began her career working for Anne Klein eventually becoming head of the team and remained there until 1985 
I wonder if Donna Koran was the one to convince Anne Klein that blue jeans, typically associated with working class people, could be considered fashionable to spend design resources on.
