Just a quick pic I did of Pepper, wearing his usual sweater and collar, probably watching a show from the floor.
If anyone's interested in him having a general "outfit" in anthro-form, this would pretty much be it. Not sure how obvious it is, but he is also wearing jean-shorts.

He doesn't have piercings of any kind, though if you want to put him in jewelry, like necklaces and bracelets, that's totally fine.

Hope you like it!
