Explanation
In Italy, the thumbs-up gesture is widely understood as a positive sign meaning 'okay' or 'good job,' similar to its use in many other Western cultures. It is commonly used in everyday conversation and is not considered offensive. However, it is less formal than a verbal compliment and best reserved for casual settings.
Local Tip
Use thumbs-up to show approval among friends or in informal situations, but avoid it in very formal business meetings where a verbal 'perfetto' is more appropriate.
