There are times when certain Bollywood looks become iconic. And you associate the look of the character with the movie instantly. Amitabh Bachchan`s blue coloured shirt and khakee pants look immediately reminds you of the classic 'Deewar'.

However, it`s astonishing to know that this look is a result of a tailoring error...yes, the superstar himself reveals that this look came about due to a tailoring mistake. He had tweeted, "The knotted shirt and rope on shoulder in 'Deewar' was an adjustment for an error in stitching... Shirt too long so knotted it."

Apart the look, Big B`s angry young man role also went on to become iconic in Bollywood. 'Deewar' also stars Shashi Kapoor, Nirupa Roy, Parveen Babi and Neetu Singh.
