  • A nice, solid colored onesie
Color: Long Sleeve Green Size: 3-6 Months
A good, basic onesie. I bought this to make my baby a St Patrick’s Day outfit and it did the job. The fabric is sturdy and soft, the fit is good. The color is true to the image and the fabric is stretchy without losing its shape. The sleeves are nice and long and the cuffs and neck aren’t tight. I used fabric paint on it and it worked just fine. A good value for the money. ... show more
