wore one's heart on one's sleeve

Showed feelings openly

To wear one's heart on one's sleeve is to display emotions openly, making feelings visible to everyone rather than concealing them.

The phrase suggests vulnerability—emotions are exposed where they can be easily seen and potentially wounded: She wore her heart on her sleeve, and everyone knew she was devastated by the breakup.
