Karen Plankton is the computer wife of Sheldon J. Plankton in The SpongeBob Musical.  Karen is a computer and, alongside her husband, tries to trick the residents of Bikini Bottom.  Karen's look in the musical is very different from the ordinary computer screen in the original cartoon series.  To recreate the costume, you'll want to focus on the futuristic aesthetic.  Karen wears green tights, silver boots, and silver wraparound glasses.  A futuristic space explorer costume is a good stand-in for an official Karen costume, but you can also get close with a silver skirt and a draped top.  Finish the look with a purple wig of your choice and some frosty lilac lipstick.
