Speaking to ComicBook.com, costume designer Meghan Kasperlik revealed that 47 Mr. Knight costumes were created by her team in-house for the series.
Being that the Mr. Knight suit is entirely white, the plethora of backup suits were on standby if one became dirty in any way.
The show's story is more standalone from the main Marvel Cinematic Universe, and there have been no announcements on when or if Moon Knight will appear again in the MCU.
