The designer, who had worked with Ghosh as a costume designer in movies like "Khela" and "Dosar", credited the late filmmaker for teaching him the nuances of cinema and style.
The collection saw free flowing anarkalis, tunic with ornate embroidery of zardosi, dhoti bottoms, crop tops, jacket tops, and sarees draped in bengali style.
Mitra played with only three colours - black, cream and gold for his clothing.
"As India celebrates 100 years of Indian cinema, we mourn the loss of one of the greatest story teller. Having worked with him on few films, I learnt the nuances of cinema and consider myself immensely lucky to learn great things from him. He made me realise that simplicity and grandeur could co-exist," Mitra said.

"I have worn a Joy Mitra before and as always I feel good. But this time it was special as it was about Rituparno Ghosh. When we lost him, I was very sad as he gave some of the best work I have done. I am happy that Joy did this and invited me," she said.
Before the show, Mitra showed some clippings from Ghosh's movies and snapshots of their photographs together.
