Unattractive → It is formed from "un-" (meaning not) and "attract" (from Latin "attractus", meaning to draw towards). The word "unattractive" means not drawing interest or appeal.
Think of 'not' ('un-') being added to 'drawing towards' ('attract') — that's why unattractive means something that does not draw interest.
