Make bedtime exciting with these fancy dress pyjamas, complete with a superhero mask and cape for an extra dose of fun! After exposure to light, the lightning flashes on the pyjamas glow in the dark, adding a magical touch to your child's night. Kids will love the playful glow-in-the-dark motifs that light up once the lights go out. For the best effect, be sure to leave them exposed to light before bedtime. The pyjamas feature a ribbed neckline, ribbed cuffs, and ankles in pinstriped 1x1 rib knit for added comfort and style. The detachable cape attaches to the neck with poppers, while the elasticated superhero/heroine mask includes an adjustable ring, ensuring it fits all children from 3 to 12 years old. With an elasticated waistband for comfort, these pyjamas combine practicality with imaginative fun for a memorable bedtime experience!
