Polo shirts are all I wear these days and I've had quite the product journey from Lacoste to American Apparel to Sunspel to random web finds.
My go to polo shirts are the Sebastian style from Orlebar Brown and Adrian/Roth styles from John Smedley. They're both pricey but the quality and the feel are pretty good (moreso for the Smedley polo since it's Sea Island cotton). Orlebar Brown does seem to fade quite a bit over time.
Happy to take other recommendations for polo shirts if you happen to stumble upon this post and have something good for me to try out.
