These are the best Hawaiian shirts!! Highly recommend them. I usually wash mine when they first arrive, and just spot iron them when dry. I only need to do this once, and from then on, they are virtually wrinkle free right out of the dryer. Beautifully made. I'm sticking with this brand!!! I think I have ten of these. Anyway, I'm 5'4" and weigh 137, and a medium is very roomy. These run a bit large.
