"I've walked once... only for Salman Khan for his Being Human charity. Otherwise, I shy away from walking at fashion shows. I feel like hiding while everybody watches you while you are walking on the ramp," said Aamir.
Aamir, 51, who looked dapper in a pinstripe suit, said he isn't a fashion conscious person.
"I am habituated in wearing wrong outfits. People don't take me seriously when it comes to fashion. So, I don't have any fear of poor fashion sense," he said.
The "PK" star, however, praised his onscreen daughters for their fashion sense and performances in the forthcoming film "Dangal".
"Sanya and Fatima are fashion queens. They have a great fashion sense. Both of them give me tips on what to wear," said Aamir.
"Watch 'Dangal' to see Sanya and Fatima's performances. They are outstanding... much better than me. You will forget me after watching them," he added.
Aamir, who featured in the fourth season of talk show "Koffee with Karan" with wife Kiran Rao, was also asked about his appearance in the current season.
He said: "I would definitely want to go to 'Koffee with Karan', but he is not calling me."
