What matting would you suggest for this print?

I work in a frame shop and I’m framing this piece for my friend. I’m thinking either a brown or gold frame off the floor (piece is about 6x9 so i’m gonna do an 11x14 frame). I want to do something really fun and elaborate with matting, I’m imagining a double mat with a rectangular bottom mat to the edges of the piece and a specialty cut one on top, and I’m thinking maybe a navy blue suede on the bottom and a light brown on top?? IDK I’m gonna play around, but I wanna hear other people’s suggestions just for fun!
