Not trying to impress others; simple and modest in style or appearance.

Unpretentious → It is formed from "un-" (meaning not) and "pretentious" (from Latin "praetendere", meaning to stretch forth or claim). The word "unpretentious" means not claiming or showing off; it describes something or someone that is modest and simple without any ostentation.
Think of 'not' ('un-') being added to 'claiming' or 'showing off' ('pretentious') — this helps you remember that unpretentious means being modest and simple.
