Supreme? Brougham? Color? Deets man, we need deets!
SMS fabrics used to have dark teal blue 87 Supreme factory fabric (Bronte style) a while back as they sent me samples. Back then they were asking like $90/yard!!!!! But I have no idea about other colors, types. You'd need some matching vinyl on the sides (I think it's Madrid style, but someone check me on that). Also a plain velour for center strip sections and head rest areas on the buckets. SMS had that too. I'm sure the upholstery shop could get the matching piping.
Colors available according to the 1987 Oldsmobile ordering book were Medium Sage, Light Saddle, Medium Gray, Dark Claret, and Dark Teal Blue
Broughams used a Knit Velour but it's kinda a thick plain velour. Same colors. I think the material styles were a made up name thing. I don't think it was industry standard, so it probably doesn't mean squat. Anyone with a 1987 Detroit book should be able to find the right material numbers.
Stuff be getting scarce, if not completely gone.
