The competition is closed and we've begun the big task of sifting through the entries picking out our favourites and trying to narrow them down to the one lucky winner. We've picked five each and they'll go through to round two, where they'll battle it out in swimsuits, the winners from that heat will then be put through a Krypton Factor style assault course, before facing the panel for a final interview.

The winner will see their actual design be printed as a real life Dirt tee shirt which people actually will wear out in public.

Round two, the swimsuits.

1/4 finals, the assault course

The finals, the strict panel of tee shirt judges.
