She’s a real prawn star.

A woman was arrested for stuffing boxers, panties and prawns up her skirt as she and a cohort routinely shoplifted from a Staten Island Costco, authorities said yesterday.

The shoplifters’ scheme involved Krystal Douglas, 26, stashing goods from the New Springville big-box store under her clothes while Charles Simboyan, 68, played lookout, cops said.

Their shoplifting spree began May 30 and ended Monday when Simboyan and Douglas were finally busted, cops said.
