A new 'glow in the dark fabric' to add fun to the outfit. Turn off the light and see the little yellow flowers glow in the dark! For the best effect, leave the pyjamas exposed to light beforehand. Short pyjamas in Petit Bateau's iconic rib knit. Picot edging and small bow on the neckline. Product certified as meeting OEKO-TEX® STANDARD 100, CQ 746/4, IFTH, fabric is gentle to skin and comfortable to wear.
