Little Blue House is part of the same company as Hatley Kids.  We love this fun Canadian brand for their Christmas pjs and whimsical designs. These fun pyjama bottoms are soft and comfy, ideal lounge or nightwear.  Made in cosy flannel, they have a drawstring waist for the best fit, and pockets. Fit is generous. Please refer to the attached sizing chart.  Fabric: 100% cotton flannel
