Carbon Costume

Mario (voiced by Charles Martinet) is the lovable plumber at the heart of Nintendo’s sprawling Super Mario Bros. franchise.  In Super Mario Odyssey, Mario temporarily trades in his signature overalls for a dashing wedding outfit as he fights Bowser for Princess Peach‘s approval.  His quest also brings him to New Donk City where Pauline resides as Mayor.  Mario’s wedding outfit includes a classic white three-piece tuxedo with white shoes, white gloves, and a red bow tie.  H also dons a white top hat with his signature M insignia on the side.  You can recreate his hat with a patch and some safety pins.  If you want to get a little closer to his appearance in the game, consider purchasing a separate waistcoat with gold buttons to replace the plain white vest that comes with your suit.

Ashley Mizuki Robbins is the main character of the Another Code video game series, in both Another Code: Two Memories (Trace Memory) and Another Code: R – A Journey into Lost Memories.

There won’t be a large feature of character backstory for this article, as I’ve only played the first one and the sequel is available on consoles not available in my region. Will update later once I’m able to acquire a copy!

Going on to the actual cosplay though:
Ashley has short white hair, and her eyes are a bit of a difficult color to pin down due to the sprite work, but I put in a dark grey that should work.
She wears a red-orange baseball style crop t-shirt with graphic detailing on the front, dark grey low-rise jeans with a white belt, black wristbands on each arm, and black sneakers with white detailing and laces.
