Do your best crime-fighting right before bed. That’s right - “Batman” gave you permission to patrol the kitchen, but only if you’re back in “the cave” (i.e., your bedroom) by 7:30pm. Now that you chased “The Joker” - aka, your brother — away from the snack drawer, it’s time to drop off the cape and head to bed before “Batman” — aka, your dad — ziplines downstairs and gives you a stern look. So, yes, drop the cape but keep something resembling the costume — something perfect for sleeping and intermittent crime-busting if a certain someone makes another run for the snack drawer. And yes, our  Batgirl Retro Girl’s Thermal Pajama Set is the perfect attire for sleeping and low-impact crime-wrangling This two-piece Batgirl pajama set for girls features glistening material and stretchy, additional warmth. Let’s break it down: The pajama shirt: Made from 60% cotton, 40% polyester.  A soft, heather-gray pajama top featuring a glistening Batgirl symbol rendered in a golden glitter-print. Long thermal sleeves covered in gray stars. The pants: Made from 60% cotton, 40% polyester. Thermal material layered in gray stars. Gray elastic waistband and ankle bands. Another glitter-print Batgirl symbol residing on the back.
