Adam Levine's clothing line is ''anti-fashion''.

The Maroon 5 frontman thinks his Kmart clothing range will appeal to most men because it shuns passing trends in favour of a timeless look.

He told People magazine: ''In a way I'm not into fashion. What I'm trying to do is something that in a lot of ways is the anti-fashion line, and not necessarily based on momentary trends.''

Adam admits his proudest moment since launching the line was seeing a singing hopeful wearing one of his t-shirts to 'The Voice' US auditions.

The 'One More Night' hitmaker said: ''I saw somebody wearing one of my t-shirts at 'The Voice'. All of a sudden I see this graphic t-shirt that this guy's wearing and he's really into it and he was kind of giving me a thumbs up. I was just really proud.''

The handsome star insists he is his own biggest fan and he has filled his wardrobe with pieces from the range.

Adam quipped: ''I kind of love it all. I love the way the leather jacket turned out. It was really simple and cool. I have definitely lined my closets with my stuff.''
