Your story reminds me of David Wilkerson. Although I don't agree with him theologically, but I have to respect him for the work he has done in the Lord.
David Wilkerson has led more hardcore street gangsters and people on the fringe to the Lord then anyone I know who has tattoos. And David Wilkerson looks nothing like them. He wears a suit, has normal hair, no tattoos, wears glasses, looks very decent....he doesn't behave like them, talk like them or walk like them.
From the mouth of the people whom he led to the Lord, the one thing that they saw in this man was love. He loved them despite all that they were.
And this is the principle that the Lord laid down for his disciples.
Joh 15:19 If you were of the world, the world would love you as its own; but because you are not of the world, but I chose you out of the world, therefore the world hates you.
Why would we then be "of the world" when the Lord specifically told us we are "not of the world?" Nowhere did Jesus teach us to be like sinners or even look like sinners to reach the sinners. The Lord never became a tax collector to reach tax collectors. He never did what they did, he just loved them. And they came flocking to him en masse.
Similarly all we need to do is to love people. David Wilkerson is the best proof of this.
Tit 3:2 to speak evil of no one, to avoid quarreling, to be gentle, and to show perfect courtesy toward all people.
