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

Nice quality
Color: Long Sleeve Green Size: 6-9 Months
I normally wouldn't spend this much for a onise but the options for this color were pretty limited. I'm glad I went with this one. Quality is nice, fit is great. Heat pressed for a Christmas outfit and had no issues.

True to size
Color: Long Sleeve Green Size: 18-24 Months
I bought this to match my toddler’s Halloween costume and it was a perfect fit. The color is spot on to the picture, it was true to size, and very comfortable. The snaps are strong, material is thick, and price was great!

Perfect for our costume
