How to make a PVC pipe coming out of drywall pretty?
Escutcheon plates come in many styles. Most common being chrome plated. Personally I would take the PVC out and replace it with chrome metal pipe. It’s a little more expensive and slightly harder to work with but looks a lot nicer and is usually what is used when exposed. If you really want to keep the PVC it can always be painted with a plastic paint such as Krylon Fusion. You could fill the holes in the drywall and sand it smooth to alleviate the need for a plate. You may want to maintain a 1/8” gap and fill with caulking  to eliminate drywall mud cracking due to pipe movement.
