Not having qualities or characteristics that are typically associated with women.
She wore unfeminine clothes that were more suited for a man.
Unfeminine → It is formed from "un-" (meaning not) and "feminine" (from Latin "feminina", meaning female or womanly). The word "unfeminine" means not having qualities traditionally associated with being female or womanly.
Think of 'not' ('un-') being combined with 'female' qualities ('feminine') to remember that 'unfeminine' describes something that lacks those qualities.
