Dezeen has teamed up with the Architecture Foundation in London to give readers a chance to win one of five limited-edition T-shirts, designed by architects including AOC, Interrobang and former FAT director Charles Holland.

Each of the five garments references different architectural drawing traditions, and particularly ones created using CAD software.
Charles Holland Architects has created a design based on a section through a Doric column ? a typical feature in the architecture of Ancient Greece.

AOC has created a play on Breton stripes, with a T-shirt that uses "typical wall build-ups" to form a striped effect, while Interrobang used CAD to create patterns of ammonite fossils.
The Architecture Foundation has also designed two T-shirts in-house, one dotted with CAD-drawn trees and one featuring a pattern used to represent concrete.
Screen-printed locally in Bermondsey, all five designs were made using water-based inks on cotton fabric.
The Architecture Foundation was founded in 1991 as the UK's first independent architecture centre. Current trustees include architects Farshid Moussavi, Eric Parry and Simon Allford, London city planning officer Peter Rees and critic Tom Dyckhoff.

Five winners will each win one T-shirt, in either small or medium size, and there is one of each available. They can also be purchased via the Architecture Foundation's website, for £20 each.
All sales of the T-shirts will help support the Architecture Foundation's work.
