The pop star tumbled down a flight of steps during her performance last week when a dancer tried to pull away her Armani-designed matador cape.
She said the garment, which was supposed to fall off her shoulders, had been fastened too tightly.
Armani responded: 'The cape had a hook and she wanted a tie, and she wasn't able to open it with her hands. That's all there is to it. Madonna, as we all know, is very difficult.'
The 80-year-old was talking to the Associated Press following his show at Milan Fashion week.
Following the incident, the star's stylist, B Akerlund, posted a picture of herself lying on the floor covered in smashed cupcakes.
It is not known whether the Swedish-born stylist, who has worked with Madonna for nine years, tied the cape herself, though she came in for abuse from fans nonetheless.
'Please improve your work, she [Madonna] is a QUEEN don't deserve this,' said one.
