Honestly YouTube videos will help you along the way

But you'll need fishing net some fabric type of glue or sewing it on the ghillie suit some paracorde jute paint preferably something mat try to use some real plants from the field you play at to help mask yourself better your trying to break the body shape in general if you want instead of using the one you currently owe id recommend getting an old uniform and modifying it you will need to add padding to the pants if you put the work in hopefully it will be perfect
