The 74-year-old fashion designer - who is famous for styling Sarah Jessica Parker as Carrie Bradshaw in 'Sex & The City' - recently dressed the 65-year-old 'Keeping Up With the Kardashians' star, who was known as Bruce Jenner before her gender transition.
Caitlyn was seen walking into Patricia's New York store wearing a leopard print DVF wrap dress, and emerged wearing a very sequinned mini skirt and heels - which Patricia had dressed her in.
The costume designer said: ''Well, Caitlyn Jenner came here the other day. That was so much fun. She was recommended by someone who works with her who is a very old friend and colleague of mine whom I respect very much.
''Caitlyn came in and she was wearing a classic DVF dress - one of the wrap dresses - and you could easily just see that what the person wears and go, oh, I'm going to show them things of that genre, but you know, you have to get to know them.''
Patricia added how ''open'' Caitlyn was to trying out different clothes, as it was a ''brand new experience'' for her, having lived as a man until earlier this year.
Speaking to Fashionista.com, she said: ''What was helpful with Caitlyn was that my friend and colleague was with her and knows Caitlyn better than I do on a first meeting. But Caitlyn was great because she was open. She wasn't fearful and it was a brand new experience for her, but she was open to it and I think she walked out happy.''
