In a tweet, the 35-year-old actress thanked the designer and said she "won't ever forget this." Neither will we.
Sunny made quite a dramatic sight, the full skirt of her outfit floating down the catwalk.
Sunny also shared a video of her ramp walk on Facebook:
Archana just loves her showstopper:
Sunny Leone, who is Canadian of Indian origin, is the first Bollywood actress to walk at New York Fashion Week. She told news agency IANS, "It feels amazing and when I found out that I am the first, it felt even better. I am very nervous about walking and just want it to go perfect."
Apart from Sunny, acid attack survivor Reshma Qureshi also walked the ramp for the designer as part of her collaboration with the 'Bring Beauty Back' initiative at the fashion week.
There was another prominent Indian face on the New York ramp - Amruta Fadnavis, wife of Maharashtra Chief Minister Devendra Fadnavis, walked for Pune-based institute Chasa Institute of Design and Technology.
Sunny Leone is awaiting the release of Beiimaan Love and Tina & Lolo this year. Next year, she will star in a special song with Shah Rukh Khan in Rahul Dholakia's Raees. She also has a special appearance in Sonakshi Sinha's Noor and Baadshaho, starring Emraan Hashmi and Ajay Devgn.
