unbutton
Open a shirt
To unbutton is to unfasten buttons: She unbuttoned her coat.
The word extends to relaxing formality or reserve—someone who unbuttons becomes less guarded or stiff: After a few drinks, he unbuttoned and told us what he really thought.
Unbuttoned suggests casualness or openness: an unbuttoned atmosphere.
