In the late 1940s, Perry was approached by Tibby Wegner, an Austrian footballer who had invented an anti-perspirant device worn around the wrist. Perry made a few changes and invented the sweatband. Wegner's next idea was to produce a sports shirt, which was to be made from white knitted cotton pique with short sleeves and buttons down the front. Launched at Wimbledon in 1952, the Fred Perry polo shirt was an immediate success. The brand is best known for its laurel logo, which appears on the left breast of the tennis shirts. The laurel logo (based on the old Wimbledon symbol) was stitched into the fabric of the shirt instead of merely ironed on (as was the case with the crocodile logo of the competing Lacoste brand).
