But the Lord said to Samuel, "Don't judge by his appearance or height, for I have rejected him. The Lord doesn't see things the way you see them. People judge by outward appearance, but the Lord looks at the heart." I Samuel 16:7 NLT
I like the commercial by Capital One that says what's in your wallet! More importantly, God says what's in your heart. Ask God to remove anything that is in your heart that blocks the flow of God's presence in your life. He's not concerned about what you're wearing or how you look. God wants your heart to be pure.
