What was nearly nude John Cena really wearing at the Oscars?

John Cena appeared to be completely nude when he stepped onstage at the Oscars on Sunday night — but, thanks to a wee bit of Hollywood magic, he wasn't. 

Behind the strategically placed envelope he held revealing the winner for best costume design, the professional wrestler and actor was wearing what's known in the trade as "modesty garment," a widely used article of clothing in film, TV and theater productions to cover actors' private parts when a scene calls for a performer to appear as if they're naked. 

Such garments  are often sourced from scrap materials, including yoga mats and leftover fabrics from other costumes. But with a spotlight on making what can be a vulnerable experience for performers feel safe, including formally in recent SAG-AFTRA contract negotiations, companies that specialize making modesty garments in different shapes, sizes and colors have sprouted up.
