The word "more unzipped" means to be more open, revealing or unrestrained. Its antonyms include words such as zipped, closed, reserved, discreet or controlled. When we say someone is "zipped up," it means they are conservative, guarded and maintain a sense of decorum. Similarly, if someone is described as "closed," it means they keep their thoughts and emotions to themselves. Both reserved and discreet imply a sense of prudence, with the former suggesting a quiet manner and the latter implying a conscious effort to keep things under wraps. Controlled, on the other hand, suggests an organized, self-disciplined demeanor that avoids excess or impulsiveness.
