Hello. I was wondering if anyone knows the difference between Prada garmets with white labels, while others have black labels. Specifically in outerwear/coats. I'm guessing the black signifies runway collection, and the white label is more of a Prada pre-collection thing? Can anyone please confirm the difference in Prada labels? Thank you, I ask because I just purchased a black Prada overcoat in techno fabric and I want to be sure it's not the equivelant of some watered down diffusion line.
