wear one's heart on one's sleeve

Show feelings openly

To wear one's heart on one's sleeve is to display emotions openly rather than conceal them.

The phrase suggests vulnerability—feelings are visible and exposed to others: She wears her heart on her sleeve, so you always know where you stand with her.

The expression often carries a note of admiration for emotional honesty, though it can imply naivety or lack of self-protection.
