Matthew McConaughey's Just Keep Living brand will sell a line of T-shirts featuring his signature phrase "alright, alright, alright".

The Oscar-winning actor first used the slogan in his break-out film Dazed and Confused. It has now become the actor's catchphrase.

McConaughey kicked off most of his 2014 awards season acceptance speeches with the line, and he used it again at the Academy Awards on Sunday night.

Now the US actor has put it on a set of T-shirts.

A portion of the proceeds from the line will benefit his Just Keep Living Foundation, which implements after-school fitness and wellness programs in inner city high schools.
