Royal Highnies Pajama Pant & Shirt. The story began as a quest to create the perfect boxer short and expanded to include the perfect pajama pant. We viewed it as locating the perfect home for the family jewels. It needed to be a custom home, handmade, including a spacious ballroom with full seating and a sturdy front entrance so that no one slips out unexpectedly. This home should be built with the finest 400 thread count pima cotton with virtually no shrinkage (on our part). One pair per package.
