(Girls) Opinion on guys who have partially unbuttoned shirts?

Anonymous
Not gonna go into much detail but at our school we are required to wear a collared shirt. Do girls like it when guys unbutton most or all of the buttons? Or should you just keep most of the shirt buttoned? This might seem minor but I'm just curious lol.

I also have a poll down below so if you can, please choose which guy in general you like the most. Thanks :D
