Great bathing suit / shorts

I’m often in between S and M in everything and these shorts are no different. I opted for medium and I’m glad I did. They fit pretty well, slightly big but I fear the smalls would be a hair too snug. I’m 5’8” 155-ish for reference. Material is great, we’ll see how they hold up in Miami next week!
