My partner has repeatedly mentioned how much they like this style of shirt. I usually see it at beach or tropic type settings but I can't for the life of me figure out what the style is actually called (these white/beige shirts with the little holes on them).

I'm in the US and I'm looking for one in a men's small or medium and would really love to gift them one for the upcoming holidays.

The one Mae Martin is wearing here is absolutely perfect and the ideal I'm looking for. If you can help me find something like it, awesome, but if you can find this specific one, even better.
