Since wrap deformer was used for suits, it might disappear upon rendering.
Select the suits model, go to Attribute Editor. You can do this by pressing Ctrl-A in the suitShape tab, tick all in the Render Stats except Hold Out as shown in the following image.
Open Render Settings, change the image size as you desire. Go to Arnold Renderer tab, increase the number of Camera(AA), Diffuse, Specular, and SSS to reduce noises.
Note that the higher the number, the longer the taken time to render.
Conduct a test

Now separate the background and character so that color correction and editing can be performed separately.
