I've got 2 Ralph Lauren polos. 1 bright red and 1 light blue. Bought mine when I was in Hong Kong at a factory outlet in 2008. I machine wash mine in a top loader washing machine on normal cycle at medium speed in cold water only. I hang them in the sun inside out to decrease colour fade. Ralph Lauren is good quality. It doesn't crease, material is still good like new and the colour hasn't faded. I've got other polos that I have noticed colour fade, crease easily and material degrades over time due to machine washing and sun drying. Other brands I've got are Tweed River, Baleno, Slazenger and Original Polo Co.
