We rotate between polos and tees, but on casual Fridays, a few of us started wearing fun prints. I grabbed a couple from
https://www.myhawaiianshirts.com/ and they’ve actually held up pretty well on site days. Comfortable, breathable, and every time I wear one the crew gets a good laugh. Doesn’t hurt that they’re easy to throw in the wash and don’t shrink like some cheap shirts I’ve had before.
