I want to achieve a plastic fabric effect like this.

but when adding thickness to the fabric, it turns out black and does not show anything behind the fabric.
If I change Ray epsilon part of the black on fabric will go but the girl`s face will be a mess.
IF I unclick thin wall and it will turn into a totally black
How do I solve the problem?
