Morphology

unbuttoned = unbutton (semi-transparent) = un + button + ed

The adjectival sense 'uninhibited, informal' is a figurative extension of the literal clothing sense, so the morphological parts are recognizable but the meaning has shifted.

Etymology

Unbuttoned can also describe a relaxed, open style, like a person with their jacket left open. The un- part means 'not' and button suggests being 'closed', so unbuttoned can mean 'open' or free from reserve.
