JK Rowling Steals The show with Her Technicoloured Coat

The coat is not bad at all, I personally wouldnt wear it but she carries it off well. I agree its a one time outfit coat. On a side note, my mother used to have a chair of the same pattern but different color.
 
I agree with what many have said - She pulls it off well but I would never be able to get away with something like that.

On a side note: She has had so much work done that I barely recognized her!
