No pattern was used for this but inspiration was! Jean over at the artful parent has made some of these dresses for her daughter repurposing stained shirts. Addy didn't have any night gowns this year and her long sleeve/pant pjs weren't cutting it. So, I used an old, stained on the tummy undershirt for the top. Cut the bottom off and attatched the skirt. Addy likes it and it is nice and cool for her. The shirt was also a little big so this should fit until it gets cold out again. Hope you like it!
