I'm Deciding How Many Buttons to Undo

I'm trying to decide what kind of summer this will be in terms of buttons undone down from my collar.

One button undone on my shirt?

A two button undone summer?

Or maybe a three button undone summer.

That would be fun.

Who knows, maybe it will be a four button undone summer.

Or maybe just no shirt.

No shirt summer here I come.
