@Paige Basically the suit that Glen linked https://www.whitearmor.net/forum/gallery/album/59-the-rs-suit/ is a suit owned by one of the owners of RS Prop Masters (they are a vetted seller) - and the biceps on the suit basically has no return edge at all on the left arm (except a tiny little dink), and on the right arm there is a little return edge on the front part of the bicep (the part that has the U shape). The bottoms of the biceps has no return edge.

So I guess you could leave just a little bit on the areas where you are unsure as @gmrhodes13 and @Doggydoc said, and just ask again later!
