Well for me its depends on how u wear the trousers, like trousers u wear under short gowns are good to wear to church...... But shorts are not suitable.....
When u are going for an interview in an organisation, u cant wear shorts, bcus u wanna look responsible and official.... When going to church u now wear short.... Is God not bigger than that organisation u are seeking job from. Why not dress responsible, dress like u are meeting the president of many countries bcus u are actually going to serve the THE ALMIGHTY, the ONE that is great.... Shorts are not suitable to be worn to church.
My opinion though
