Kolkata, Sep 13 - Bollywood actor Irrfan Khan Sunday said he has always kept away from endorsing liquor and 'pan masala' (chewing betel-nut-tobacco mix) products as he feels it is 'not the right thing to do'.

'There have been so many enquiries (from advertisers). But I have never endorsed such products. There are no moral issues involved. But it is just that I did not feel doing them. I feel it is not right,' Irrfan said after walking the ramp as the showstopper for designer Abhishek Dutta's Spring Summer collections 2010 at the Kolkata Fashion Week-II here.

'I have only endorsed products I can rely on,' said Irrfan, noted for his sterling roles in films like 'The Warrior', 'Maqbool', 'Haasil', 'The Namesake' and 'New York'.

Branching into Hollywood, he has also played the role of a police inspector in the Oscar winning 'Slumdog Millionaire' and starred opposite Angelina Jolie in 'A Mighty Heart'.

After blazing the ramp amid applause from the audience with his signature-tune confidence showcasing a brown jacket, white t-shirt and cream trousers, Irrfan also spelled out his style statement.

'I prefer clothes which make me feel comfortable. For me, comfort comes first, then style. And the dress should also camouflage my bodily defects.
