The Twin Tipped Fred Perry Shirt. Made from our classic cotton piqué, in a contemporary fit. The M3600 has slightly slimmer proportions than our original M12 tennis shirt, with neat cuffs and collar. Legend has it, our twin tipping came about when a buyer from Lillywhites requested the addition of football team colors to Fred’s plain-colour tennis shirt. Only we use tipping in the ratio 5-4-4 and it’s a part of our DNA. An interpretation of our original Twin Tipped Fred Perry Shirt, the M3600 has a more contemporary fit. This colourway replicates original tipping colors from our 1964 catalogues. It comes with a history, and each new generation adds to its legacy. Always different, always the same. All items in our e-bay store are new with labels and/or boxes, original and available at our.
