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 pyjama bottoms are soft and comfy, ideal lounge or nightwear. The waist has an elasticated band that doesn't dig in, and is super-stretchy. Fit is generous. Please refer to this sizing chart before ordering, bearing in mind they are a big fit.   Fabric: 100% cotton jersey
