Shink wrap modifier and alternatives?

Hello again everyone, I have started on a new project and I have run into a slight problem, I know there is a solution out there for it I just can’t find it. I am trying to make one mesh fit another using the shrink wrap modifier, but every time I do it flattens the mesh and looks really bad. ( https://gyazo.com/33d65de081630bcdecc665427d1538f2 )

I saw a tutorial on you tube of a guy using a shrink wrap modifier on mesh and it NOT flattening the object, but the tutorial is in german and I can’t understand his instructions.

If any one can help me with this that would be amazing, i am trying to get one mesh outfit to fit the body I am working on, thank you much in advance for any help that is posted here.

I sholdn’t be posting this here because of the apparent reasons but what the hell: https://www.youtube.com/watch?v=yNWcEG60qtY

I hope Jonathan Williamson will forgive me.
