I found the information for
David C. Robinson - Costume Designer
There is suppossed to be contact information listed for the designer, but you have to subscribe to the service.
face book is a good place to start. You can go to his name, and also check Queen Latifah's facebook page. There may be a few, but look for one that is updated regularly.
Hope this helps.
As per the credits from the movie David C. Robinson is also listed as costume designer.
I thought my document contained information regarding Tsigie as well. I was basically saying that I thought facebook would be a way to gain information.
