I am a man.What parts of the body has to be covered when I make a brocho.

Shalom and thank you for your question about modesty for men while praying. Wearing trousers is a must, and it is very appropriate to wear a garment on the upper part of the body, as well as a kippa on the head. When praying the Shemoneh Esre, a garment on the upper part of the body is a must.
