Kangana, 27, who is known for her role as a supermodel in Madhur Bhandarkar's 'Fashion', looked uncomfortable and even stopped at the middle of the runway to manage her black body-hugging off-shoulder gown designed by grand finale designer Namrata Joshipura.
The 'Queen' star also apologised and took the blame on her for not making it to the mark.
"I feel her show and collection were brilliant but I feel bad that I let her down," Kangana told reporters after the show.
The grand finale opened with a high-octane live music performance and neon lights set up gave a dramatic feel to it. Namrata presented her collection 'Electron', which was inspired by her new fascination artificial intelligence and brain mapping.
Kangana was highly impressed with her collection and said her style sensibilities matches with the designer.
"Namrata is a good friend of mine and I relate to her designs. She also loves quirky stuff like I do. She used something metallic thing on the lips which I really liked and wanted to put. We have same attitude towards fashion. I am thankful to Namrata for giving me chance to walk. I love getting dressed up," she added.
