Although this dress is made out of pillowcases....it's definitely too cute for sleepin' in. Boutique Mia sells this pattern as well as many others. What is even cooler than the print and design of this simple little dress...is that it can be worn twice. What I mean by that is your 18 month old can wear it as a dress....you can pack it away for 3 years and then when she hits 5 years old you can bust it out again as a shirt....PERFECT!
