open-front shirt but it mostly describes a shirt that is supposed to be open in front, as in, it has no buttons. What I'm looking for is an adjective to describe when someone chooses to keep the buttons of their shirt or the chain of their tracksuit open. I thought about using
open-chained but it reeks of incongruity ("open" and "chain" doesn't really go together).
So, is there an adjective to describe what I mentioned? An example sentence would be: The guy with the _______ tracksuit is the favourite to win this year.
