Italy's Palermo and occasionally Juventus are well known for wearing pink shirts*. In recent years, many clubs have worn pink for special games or occasions, often in support of Breast Cancer. Here are the clubs I came up with. There are probably a few more (especially in Italy), so feel free to let me know and I'll add more pink shirts to the list.
CEREZO OSAKA (Japan)
SHAMROCK ROVERS and BOHEMIANS
*Juventus started out with pink, but switched to the Black and White stripes (a copy of England's Nott's County, where the shirts were shipped from) after realizing the pink shirts got bleached after washing and the colors faded. They've had pink shirts on and off since then.
Here are a few more Historical Pink Kits from England (from the excellent site, Historical Football Kits)
BOLTON WANDERS (1880)
