I wore Fred Perrys all through the 60's. I have holiday photos of my dad, his mate, me aged about 11 and my brother aged nine all wearing FPs in about 1964. If you bought a Tennis shirt that is what you got. There wasn't a wide range of brands available. Original skinheads did wear them in our area. John Smedleys with the larger collar were worn by my older Mod cousins.
