seeking buttonless collared summer shirt

Hello! I’ve been fruitlessly searching for a shirt like this one and have struck out with dozens of searches. Words I’ve tried: johnny collar, buttonless popover/pullover, v neck collared casual shirt, buttonless guayabera, tunic shirts, and so on All searches either give me a sweater polo, which is not the material i want, or a typical casual camp shirt with buttons, which isn’t quite right either. Any insight or links would be appreciated! I’m in the US btw
